Not me , I guess everyone belieave on Bitcoin but investing my life savings ? I would never gamble like that.
I only invest amounts that I can afford to lose.
I agree with you.
In today's world nothing is 100 % safe.
Even big banks or even whole countries can collapse (Argentina for example ) so to put trust and life savings into Bitcoin is really not smart move.
Invest only amount you can afford to loose and this is the best advice for all bitcoin users.
