I feel like we have simply touched the surface of "Bitcoin Usage" and by that I mean, it is only used by a limited number of individuals worldwide. Not everybody goes through the sophistication of chart reading, signing up on exchanges and following blogs and those who do have multiple intrinsic needs. Mostly are just there to make money, and in this world lots of people have used nefarious means to gain money. Bitcoins are no different, and they will be used as leverage, to launder, be used in fraudulent schemes and acquire ransom money. But that is a flaw of human nature, not Bitcoin. Criminals traded in gold, silver, drugs and even cattle and women millenniums ago but we don't curtail their availability. This rationale is what gives me hope for Bitcoin!
