Sure, it depends on how you hold your private keys but there is more risk associated with that then holding your money in a bank. We will figure that out one day, but right now banks are safer.

but if something happens..

The possibility of "something" happening is extremely low.
If @whatsup wants to take a bet, id bet all my steem and the rest of my crypto portfolio that nothing close to the great depression in magnitude will happen any time soon, if ever.
hehe.
We can talk economic stagnation or depression all we want, but id say thats pretty silly when wer sitting at 0.4$ at 90% down from ATH. :)
