Verified member (highest level possible) at Poloniex and Bittrex from 2017, but that didn't stop either from at times blocking my account and/or just delisting wallets without notifying me.
Just because they haven't done anything to you doesn't mean they won't down the line.
They're both great services and pretty much reliable (I still use Bittrex occassionally) but the moment you're done with them, best keep your Bitcoin on your own wallets. Just not worth the risk leaving it to chance.
I can’t speak for the OP as he’s a new account & I don’t know if he’s done anything shady which forced them to block his accounts. I am very surprised that they acted like this towards you buwaytress, a trustworthy account here. Did they give you a reason?
You are right but sadly many crypto related exchanges doing these tricks for years they never feel shame for their acts like these Bitterx few years back locked thousands accounts and blocks millions of USD worth funds without any reason as they was changing few polices but in OP case we need some more update what is main case why this all happen.
