It's good that bad centralized exchanges are delisting coins. The more they remove the more clients will leave the exchanges.
And what are the good exchanges?
Decentralized exchanges (DEX) i guess, but the liquidity is just very low there and the fees very high.

and understand the regulation that is applicable to their exchange and their crypto listing (Kraken, Binance, Coinbase, Bitfinex etc)
It is the smaller centralized exchanges that are feeling unsure about the (mostly US) regulation and rather then putting time and money into setting up
internal monitoring tools, so they as exchange comply with FATF regulation (travel rule) and US-specific regulation, they rather just delist certain coins.
ShapeShift and Bittrex are examples of those smaller centralized exchanges / service providers that operate in such a bad manner.
Also to consider is how regulation differ between the US and the European Union. The EU Court of Justice prohibited the FATF travel rule in Europe because it
undermines the privacy of European citizens. They basically banned it in the EU. Same with the Privacy Shield, an privacy agreement between the US and the EU.
The EU Court of Justice invalidated that treaty in July 2020.
European exchanges operating in Europe have in general more relaxed crypto regulation, then US exchanges operating in the US.
Simply because in Europe privacy is valued higher and protected better, then in the US.
