Well, look at it this way. A financial collapse of catastrophic proportions will happen in our lifetimes. When this happens, and it WILL happen, BTC will rocket to the moon. So one could argue that BTC is a guaranteed investment to yield huge returns. Just how long you have to wait is the question. And i'm not talking about BTC price increasing as a result of of the devaulaton of the $.
i too believe that a financial collapse will eventually happen, and i used to think that bitcoin would skyrocket in that event. nowadays, i don't believe in that happening so much anymore. there's going to be a lot of panic and fear, and people are going to want something tangible to hold in their hands. also, if we experience something similar to the great depression, the internet may not be as easily accessible as it is now.
