Do you think that China is controlling/ruling bitcoin yes or no?
Really? Mark Karpeles proved that one guy and two bots can manipulate and control the worldwide Bitcoin exchange rate.
Isn't it curious that currently Coincheck in Japan (last known home of Mark Karpeles) has double the volume of the next two largest exchanges. Isn't it funny that Coincheck became the largest exchange in the world right about the time Karpeles was released from prison. Wonder if he started giving pointers to the Yakuza (Japanese mafia) in prison to keep the number of ass rapes down to a minimum and they helped him restart the old business with stolen bitcoins. LOL
he could not do it now. At present, no exchange controls more than 20% of the world trade
Well, you seem to not follow recent events in Bitcoin world very closely
The irony is that while it is certainly true that no exchange controls the majority of coins (at least, nominally), right now we basically see the same process going on. I refer to Bitfinex, obviously. Two weeks ago clients of this exchange started to have issues withdrawing their fiat funds and later they couldn't make fiat deposits either. And Bitcoin (as well as other cryptocurrencies listed at this exchange) started to be traded at a premium there. And what do you think? The price at other exchanges started to rise too just because Bitfinex happens to be the largest Bitcoin exchange in the world (or one of largest). The bottom line is that we haven't yet gone too far from the effect we had seen at Mt. Gox
