Nobody is safe even the FIAT money I think but for me Bitcoin is more safer than FIAT in terms of robbery, so in short nothing is safe it's just how you can safe it.
How are you determining whether or not something is safer that BTC, etc? Biitcoin I though would be safer because there is no way to beat the system and take it. Unles your account is hacked and such, there is not much of a way to loose it. The same can happen to FIAT and all other coins. Just wondering what basis you are using to make this statement.
