https://support.bittrex.com/hc/en-us/articles/360001609031-Wallet-Removal-on-March-30-2018The majority of these coins are shitcoins where it doesn't play any role or make any sense in the market. It is bad news for the people who hold those coins. So finally we are left with the quality coins so that is safer for people us to trade.
