I would like to ask: What is the big problem with the current system which requires this change?
Why does this change need to be prioritized now, when we are desperate for things like a stable client?
I think we should avoid creating a huge overhand of vesting BTS which people know will be unlocked at some point in the future. This could make people think "Well, if I invest in BTS now, I'm going to get dumped on in the future as soon as those shares become unlocked".
