Some of the reasons that attract me or others as well to Binance is the easy registration process, very easy to understand user interface even for the first timer in crypto space, Altcoins keep on increasing and one which is not worth is being removed, good liquidity on the exchange and good safety feature as well.
Crypto related services are sometimes really hard to get even registration done - I totally agree, binance helps with this.
But its liquidity was that great during this March dump, afaik kraken and bitfinex were providing majority of liquidity on the global market.
binance's wide choice is something I appreciate the most honestly
