Banks have run at a loss on many occasions so it wouldnt be a surprise they would attack Crypto markets. Personally feel they are threatened by the whole structure of crypto. People will never look at banks again for investment options. The last respectable savings I ever had off a bank was 5% in my young savers account back in the early 90's.

I also believe once the banls have helped push the price down they will be amongst the first to invest at the floor price.

Personal oppinion of course.
