there could be a bit train so anyone can start it by doing a mathematical series of bit donations. for example: someone donates 1 bit, some other one donates 2, 3 etc. or someone donates 100, 200, 300... or even 3, 6, 9 or 5, 10, 15 etc.
doing a long combo unlock more bit emotes.
there could also be some high level unlocks for 100 or 1000 bit chains.
