The BKC fee and Nu

Because B&C will not feature us dollars. By establishing a peg at B&C we would counter market movement dictated by supply and demand. Say we have a 20k peg and on Okcoin CNY/BTC drops 20% traders are the first to respond to these moments instantly dumping BTC into our buy walls, leaving us with a net 20% loss on our liquidity provision. Hedging is already a huge liability in liquidity provision with the BTC/NBT pair if we would allow hedging on our main trading pairs we will go bankrupt in weeks.

The difference is other exchanges use USD or an equivalent, so our NBT/BTC pair needs to be in sync with our NBT/USD pair otherwise traders could take advantage of arbitrage between the pairs.

I would favor a new dispensary for Nubits where people could directly buy or sell they Nubits from Nu (maybe with a tiny fee attached to it), that way we effectively wouldn’t need other exchanges except for visibility and exposure. However until there is an actual need (B&C) for Nubits this is not applicable.

But other exchanges don’t? Bring it on. If other exchanges do then this is just a price feed problem, mitigated by the parametric order book. This issue is exactly the same as liquidity provision on any other exchange, B&C is not special.

Why is it hard to be in sync with something that is always equal to $1? NBT/USD pair has no price feed for Nu, it is equal to $1. That’s the whole point. Therefore NBT/BTC tracking is equivalent to BTC/USD tracking. Again, this is the same as any other exchange. Why we would avoid providing liquidity on B&C just seems to me to be completely counter productive.

What do they trade for the Nubits? If USD, who’s going to deal with the KYC? B&C is our ‘dispensary’, that’s the entire reason why we forked. In this very thread I am arguing for having literally 0 fees short of custodian costs on dispensing NBT at BTC prices of our choosing. Why would that be a bad idea for Nu?

USD or anything else we choose, the whole point is having Nubit easily and readily available at one dollar each. If you want to dispense additional Nubits through B&C you could easily give a custodian Nubits to sell on the exchange at slightly above market value and even issue buybacks at slightly below market value this however is very different from maintaining a strict peg which would constrict normal market movement and open Nu up to hedging. This would also be profitable to Nu on its own even with having some BKC costs.

You cannot sell your bitcoin for dollars on other exchanges if no one wants to buy your bitcoins for dollars. Just as you shouldn’t be able to sell your bitcoins for nubits if no one wants to buy your bitcoins. No exchanges provides the dollars people use to trade with as dollar buy/sell walls on the USD/BTC pair, nor should B&C provide the dollars (NBT) for people to trade with.

It’s been recognized that NBT/BTC pegging is a money-losing business. Nu is paying for it as a promotion or a customer acquisition operation, because BTC is the base currency in the cryptoworld. The cost of it could be very high if BTC price crashes or major exchange defaults. B&C is good at cutting down the exchange default risk.


Correct, because a third party like Nu or USDT does it for them. I can’t help but think you’re just arguing against BTC LP’s in general. I could argue the merits of liquidity provision for holding a long term peg as a marketable product, but I’d really rather not do that in this thread.

I disagree. What you are ignoring is the spread after fees and the parametric order book. High trade volumes are not bad for us, they are very very good, so an exchange where NBT/BTC is the main pair should actually lower our liquidity costs, not magnify them. As for the speed of the B&C exchange, I have outlined a process that could be done quite quickly, moving orders around by the minute. This is definately on par with the pybot software.

If an LP were to propose a grant that offered to provide Tier 1 liquidity at a fraction of the reward as the other pools, would you really turn it down? How would you justify that?

Most of Nu’s liquidity cost is due to exchange rate (BTC volatility) risk, which B&C can’t help with. B&C might cut the current 10%/mo rate by 2-4 percentage points.

Note that B&C is still not delivered so how efficient the system works is unknown.

Right, but the parametric order book can help a big deal here.
By the time BCE is operational this parametric order book should be available - it’s planned for the next release of NuBot

In addition to the vastly reduced exchange default risk trading on BCE NuBot improvements can reduce the costs for liquidity providing even further.

In the end the risk can be mitigated by a bigger spread between buy and sell walls (and in the future by the shape of the parametric order book). It’s up to Nu to decide how much to pay for what tightness of spread on the NBT/BTC pair.

I wouldn’t wonder if we face times in which the spread for NBT/BTC on BCE won’t be as tight as the spread of NBT/USD pairs on centralized exchanges.
After all Nu guarantees a peg of 1 NBT to 1 USD and not to the USD equivalent in BTC :wink:

I agree. But high spread in nbt/btc is not happening (B&C or not). It’s telling something,

It’s just telling us what the default parameters of our bots are. The parametric order book is a push service. Orders will be placed based on a bigger picture rather than always at some fixed spread like they are now. B&C lends itself to this concept nicely by providing a method for publicly verifying orders (talking to the decentralized block chain instead of to a centralized exchange server).

To me, these 3 statements appear reasonable and yet not compatible.

Nubits are a third party to B&C, poloniex is not paying to upkeep tether USDT liquidity buy and sell walls on their exchange and I don’t see why B&C should pay Nubits to do so either. Explain to me why B&C would want to pay for a Nubits liquidity pool at B&C, since that’s what you’re asking B&C to do.

[quote]If an LP were to propose a grant that offered to provide Tier 1 liquidity at a fraction of the reward as the other pools, would you really turn it down? How would you justify that?

As stated earlier I don’t see why B&C would want liquidity pools on its trading pairs. No exchange does this and with good reason. Also I think it would be far more beneficial to Nu to just sell and buy Nubits for 1 dollar without trying to upkeep buy and sell walls on B&C. When B&C is live people will need Nubits you don’t need to maintain costly inefficient pegs to sell them to people.

If the NBT/BTC price on B&C will get out of sync with other exchanges and thus a “broken peg” there will be traders profiting (arbitrage) until balance is restored. I don’t see a need for liquidity pools on B&C except for maybe the first few weeks to get some instant liquidity going. After that the traders themselves will provide the liquidity just as on every other exchange.

I am 100% not saying that it should. I am saying that B&C should allow Nu to operate LP’s at 0 fees. That is distinctly different from paying for the operation, as the only cost to B&C is blockchain space. This will not lower dividends, it will amplify them. It is not costing B&C money, it is allowing for more trade, thereby helping to generate money for B&C.

This is false. Poloniex does this, Bter does this, Bittrex does this, CCEDK does this. Practically any NBT pair with volume does this. The exchange doesn’t pay the liquidity costs, Nu does. CCEDK has mentioned that it would love to drop the fees for LP’s if it could figure out a verifyable way to do that. We have that opportunity on B&C in ways that centralized exchanges can only dream of.

The tendency for arbitrage (i.e. price slippage) is going to be equal to the sum of all fees. That includes the network fees, but it also includes the trade fees on the exchange as well as withdrawal fees. That means that when Nu wants to sell 1 NBT for some BTC it has to pay the trade fees and withdrawal fees on arbitrary exchanges. That’s wayyyy less efficient than simply trading on B&C.

Why would we make B&C if we aren’t going to use it? You think trade volume will magically appear overnight, but without liquidity it will be a long time before people start trusting B&C exchange.

So you even agree that there is a clear benefit toward stimulating trade using liquidity.

Is your argument that liquidity provision on B&C is not worthwhile for NSR holders, BKS holders, or both? Because you’ve simultaneously said you don’t know why Nu would do it and you don’t know why B&C would do it.

I just cannot fathom why you think B&C is a bad exchange for Nu to operate a liquidity pair on. That’s the entire point of B&C. Let me just quote from JL’s initial announcement of B&C:


I agree with Jordan Lee about the synergy between Nu and B&C, I mean the win-win situation:

  1. Nu LPCs provide trading volume for B&C, and an important basic/stable currency: NBT, which makes up the absence of USD FIAT.

2)B&C provides Nu LPCs a safe exchange, almost, if not completely, immune to hacker/thieves.

But I am opposite to giving 100% free discount to Nu LPCs on B&C, because

a) the CMC will delist NBT volume if there is no transaction fee.
b) It’s unfair to those BKS holders who have no NSR, just like me. :smile:

I’m not saying don’t have a Tx fee. I’m saying Nu should provide BKC to LP’s and B&C should provide BKC to Nu. There will for sure be a Tx fee on the blockchain and for all traders.

If Nu said that it would provide 10K liquidity if B&C forced Nu to buy BKC for $1 a piece, 20K if it’s only $0.5 a piece, and 40K if Nu gets free BKC for liquidity operations, which would you vote for a s a BKS holder?

BKS holders are not begging Nu LPC to trade on our exchange. BKS holders care about revenue by charging trade fee(such as 0.2% on BTC-E), if Nu LPCs wouldn’t pay that trade fee(not the trasaction fee on blockchain, I mean the buy/sell fee), I would vote to ignore any request from Nu company.

B&C can survive WITHOUT Nu at all, eg, we can survive by providing BTC/LTC, BTC/Doge pairs. Yes, NBT stable currency is welcome, but if bitUSD/USDT are more popular, I as a BKS holder or potential signer, will vote for more bitUSD/USDT rather than NBT pairs.

B&C is neither a branch nor a subsidiary corportation of Nu company. For B&C shareholders, any stable currency’s success (TRMB,bitUSD,USDT,NBT) is welcomed, we don’t care about your liquidity, we care about our trade volume which is related to our profit.

It appears to be a good choice for both Nu and BCE to vote for option 3 :slight_smile:

All decision should be voted by shareholders, not by we several men.

Personally I like to reward something to attrack Nu LPCs in early days of B&C operation, but if in future B&C business grows big, I dislike that expenditure: why should B&C give money to another company? At least NBT should compete with other stable currencies and satisfy BKS holders, otherwise, you can go.

Even if NBT liquidity providing were in any way sponsored, the fee from other people trading thanks to NBT liquidity on the exchange were available in full height.

Would you rather have (knowing that it can’t be calculated like this) 0.2% fee from each side of the trade with little volume “thanks” to low liquidity or 0.2% fee from one side of the trade and maybe less than 0.2% fee from the other side with way bigger volume?

If BCE can only double the volume (I’m still aware that it can’t be calculated like this) with 100% sponsored liquidity providing (not saying that 100% is necessary), BCE is at break even. With more than doubling volume, it’s for the benefit of BCE.

I know which way I’d like to go :wink:

Because BCE can make even more money by “investing” some money!
Reasoning see above.

I tend to disagree with a lot of this post.
The lead architect is the same, the dev team is the same and although the initial funding that would have made BCE a 100% subsidiary of Nu wasn’t successful, 85,000 BKS were paid to NSR as dividends.

That makes 85,000/184,811 = 0.459 or 45.9% potentially in the hands of NSR holders.

I won’t find out, but I wouldn’t wonder if some more percent have been sold to NSR holders.
At the very start Nu and BCE are tied to each other.
That might change over time.
But liquidity providing to get the ball rolling is an important task for the early phase of BCE, a phase where Nu and BCE interests are economically tied to each other.

BCE needs to care about liquidity, because that’s the key to volume!

It’s as convenient for BCE to have good connections to a provider of a pegged currency as it is for Nu to have good connections to a decentralized exchange :smile:

If bitUSD, USDT or others approach BCE to provide liquidity for better conditions than Nu does, fine. I haven’t seen the queue of stable currency providers in front of BCE’s doors so far…

Option A: The largest exchange in cryptoworld with 1millions USD revenue annually.

Option B: The 4th largest exchange with less trade volume, but 1.2 million revenue annually.

Definitely I will choose B.

That is possible because the revenue is not a simple proportianal relation to trade volume, I guess if everything else being equal, if you raise the trade fee, initially the revenue increases and then drop.

Revenue = (trade volume) X (trade fee rate)

BKS holders’ task is to find the opitimized trade fee rate which gives us the largest revenue. A proper fee rate.

Perhaps B&C holders should have more ambition than some Nu people think: this is a credit broken cryptoworld, we don’t trust Mtgox, nor BTC-E, Poloniex, etc, in fact I trust none of them.

B&C’s goal should be as high as being a famous, big, perhaps top 5 exchange in cryptoworld.

To sum up, how much invest should be put into reward Nu LPC, will be fully discussed and voted by BKS holders. For a new born and not rich Company(B&C), it’s not wise to give too much money to Nu, unless there are quite some big Trojan in B&C’s “board of directors”/decision making process. :smile:

Revenue = (total transaction size in byte) X (fee in BKC per byte)

What about Option C:
the 30th largest exchange with very low trading volume, because of lacking liquidity and only $12,000 revenue annually?
I’m in favour of incentivizing liquidity providing (even at an expense!) to turn Option C into Option B :slight_smile:

Then I need to adjust the formula:
Revenue = (total transaction size in byte) X (fee in BKC per byte) - expenses
