Do realize that BItcoin can go to zero. Maybe everyone has their ideas about what the chances are that that happens, but no one should think it's 0%. So invest wisely.
No duh. The chances are low. You do realize that any form of money from any country can go to zero to right? You do realize that all countries are technically in debt right? All things have value as long as people believe that there is value in it.
I mean, look at the Zimbabwe dollar! It's not even at 0!
