I can't deposit my clams to Yobit, it says clams wallet in maintenance and I live in USA so I cant deposit to tradesatoshi.  Is there a way I can doposit to that POS wallet?

I am disgusting with Poloniex for I have lost so much money from them especially because the random selling of all my margin alt/btc ratios on 9-30-19 and sold my altcoins to pay for the losses when they never mentioned a date that U.S customers had to closed margin positions so I assumed that I could hold for a very long time and the timing could not have been any worse, when BTC dominance is at 69%  .
