For the moment, we have a problem with block, so you can't do anything (play or send money). If you let your money to another person (exchange, wallet online etc.) you risk to lose it if the person/exchange/wallet online is hacked. If you let your money in your personal wallet, you can't lose all if you have a trojan/keylogger, or if your computer die and if you don't have backup/good security... Do what you want, but understand the risk !
