I agree with you. If I had used an Electrum wallet instead of Bitfinex I wouldn't have had any problems.
When I opened this issue, I had $30,000 in my account, now it has decreased to $25,000. Even if Bitfinex let me withdraw it today, I've lost $5,000.
They really don't care how much you have lost in fiat value because the asset is in form of crypto. So to them, 1 BTC in Jan 2019 = 1 BTC today.
Was you account completely blocked?
If I were you, I would have tried to convert the BTC to USDT so as to avoid it from dropping in value during market price decline.
what a crap exchange!!!
