Bitcoin scene seems to play out like a huge MMO without a single GM.
Or a wild west without guns or sheriffs.
Without potential to inflict violence ( by police, courts, army or lynching ) scams, abuses and opportunistic
stunts seem plentiful.
I think this is a hard lesson for people so used to blindly trusting others and turning to the government when it doesn't turn out well. Use the tools available to you to determine if someone is trustworthy. If you're not sure, get assurances or don't get in further than you're willing to lose. If all that fails, learn a lesson from your mistakes?
How many people are going to lose their money in online wallets before they realize that they can run Bitcoin on their own computer?
