Is it our friend Elon Troll Musk again?
There's a rumour it's China this time, apparently one of the biggest banks has stated they will systematically close and report any account that has crypto dealings.
Seems like it's plausible this is the explanation this time, but nobody can be 100% sure.
Indeed the actual "temporarily" decline is related to China, as usual.. From what I read, it is targeting the mining activity in the country. Obviously this isn't the first nor their last move to restrict freedom to access cryptocurrencies..their point is to divert people from it so they can adopt their virtual ¥ easily.
Finally as Danny said, where did you see the decline /#HODL
