Why would ppl flee from his pool, if tycho is giving them EXTRA FREE MONEY?
I would certainly expect more people to join him if his pool is paying 200% extra!
After all, if it wasn't for the greed, you'd all be Folding for a greater cause.
Which is exactly what i fear most. Let's forget about deepbit and tycho for a bit; what would happen if a malicious user creates a pool that gives, say, 200% bonus to every miner? He would easily get >>50% hashing power as honest pool owners obviously cannot compete. At that point, he could easily launch a huge double-spending attack to make for all the bogus bonuses he gave away and much more.
Isn't this a possibility?
