Question: If it's China that's doing the selling and driving the price down, who are they selling to? And would that not lead to a redistribution of bitcoin? Also, is there any proof of China as a whole being responsible for the drop? I'll admit I read absolutely zero crypto news.
Bitcoin is ramped on CNY exchanges, with volume that is likely 95% fake, if not more.
Large quantities are then dumped on USD exchanges, which is what the Chinese Bitcoin Cowboys are really interested in...i.e. wealth out of the country, wash rinse repeat.
....except Western investment interest in Bitcoin is getting increasingly thin (just look at the cross exchange volumes), which means the Chinese Bitcoin Cowboys can offload increasingly less Bitcoin into USD with each manufactured pump n dump, but then there is only half the volume of Bitcoin being created now as there was before July 2016.
There is nothing that can be done about it, unless somewhere in the world, can offer miners even cheaper energy than is offered to miners in China. If that were the case then I suppose if a Western based cabal had the motivation to do so, then they could open up shop in this ultra cheap energy economy, and do exactly what the Chinese done. Namely, intentionally crash Bitcoin and keep it suppressed for long enough, to force miners with too expensive energy bills, to shut up shop, and then when all those guys are out the game, allow/force the market to rise again.
But even in the unlikely event that some western venture capitalist cabal had the means and the motivation to give the Chinese a taste of their own medicine, Bitcoin would still have the problem of being controlled by a very small interest group.
