I'd say, some governments... some institutions, some people, but overall it's all about the mighty Dollar :-D
Bitcoin is basically... nothing!! :-(
Something that has nothing material as back up and relies on people's perceptions. As seen so far, from $20k to $6000 on one month... ?!?!?
I'm sure some people got rich at other people's expanse, but where and at what point will BTC produce money other than speculation?
What's sustaining the growth???
To many questions to few answers for the reasons of cutting off the bank and fees... BS, sorry
