We need to move to nsr/nbt eventually. Given the low liquidity of NSR, there will be people who want to skip BTC/fiat and go straight into NSR, so that’s where we grow tier 6 operations from nil. So we can let tier 4 have multiple assets like BTC and NSR, and use them in their respective markets to offset excess NBT liquidity, and it will be more effective than just having either one. If tier 6 becomes mature enough then it could spin off as a stand-alone unit that doesn’t need full support from tier 4, fulfilling our decentralization ideals.
And I’ve always been a bit disgruntled with exchanges taking all the profits but giving us all the default risk, so I’d love to be able to save some exchange fees, even if it means we have to pay up to an equivalent amount to shareholders who’d be in charge. Buying NBT from ALPs is a good idea - it would probably save us from the “can of worms” you mentioned for reducing sell-side liquidity payout. But so is buying NBT using NSR, and I don’t see why these two can’t co-exist. That said I’m not in favor of using Tier 4 to buy from open markets as a regular occurrence.
Anyway, I admit I’m hung up on tier 4 because we need to cultivate a workforce within the community and among shareholders. There’s a steep ladder (I’d say it’s actually a rocket) from being a peasant shareholder to being a paid anything, and the result is we’re putting too much work in the hands of just a few people who have more important duties to attend to. So I just need any excuse to bring community-sourced ideas into tier 4.
