The sad irony of it is there are more credit/debit card fraud annually and hacks surrounding fiat currencies than the sum of all the crypto frauds/thefts.
It comes back to educating people that private keys are as good as cash and that trusting a third party (example, an exchange) means you really don't "own" the coins. The no-recourse in terms of chargebacks is a double-edged sword. As for other scams like ponzi's guaranteeing to double your money (cryptodouble)...those are a dead giveaway that people are going to lose coins. While they may not be regulated expansively, anyone running these sorts of games stateside should be aware of the SEC taking notice.
If spreadcoin remains to be practically 100% solo mining and adds all of darkcoin's features, spreadcoin will become my currency of choice.
I'm not going to be the only one.
