Hi Rodchi
There could be any number of reasons, but I think it’s likely there are some NSR holders who are purchasing from Jordan for the sole purpose of selling to the public for a higher price. Once NSR purchase restrictions are tightened, I would expect the BTER price to begin increasing. An important thing to remember is that there are approximately 500M NSR in the hands of shareholders right now, and BTER’s daily trading volume is often below $10,000 US. By all accounts it seems that the large majority of shareholders are planning on holding NSR for the long-term, so that they can contribute to and vote on the Nu network.
It’s up to each custodian to provide a dividend payout schedule. @KTm for example provided a payout table in her initial proposal.
The Nu white paper addresses your second point. “It is likely custodians will demonstrate they hold a substantial quantity of NuShares so that shareholders know custodians’ interests align with their own”. NuShares will be valued based on the anticipated future dividend streams provided. If a custodian stole the dividends, the value of their own NuShares would suffer. It is an important reason why existing custodians have shown they hold significant NSR reserves, and that the development team is familiar with them. It’s unlikely a random newcomer to Nu would be able to get majority shareholder support to be a custodian.
From https://nubits.com/nushares/voting-mechanics:
Share days are accrued by shares if they are undisturbed (not sent or staked) after becoming a verified transaction. After seven days, shares are fully matured (usable for minting). Holding shares beyond this date has no impact on the difficulty of minting a block. This creates an incentive for NuShareholders to mint as soon as possible.
Jordan Lee also addresses it here: Short guide to minting and voting for shareholders
In short, your computer’s processing power has no effect on how often you will mint NuShares.
From http://discuss.nubits.com/t/short-guide-to-minting-and-voting-for-shareholders/446:
Presently it will take an average of 5 weeks of minting attempts for an output of size 10,000 to find a block. This will go up as additional NuShares are distributed.
