Unlike stock market, listing a coin in cryptocurrency market is very easy, as long as you can bear the fees. Isn't that the reason why so many exchanges are being created day by day. Some top exchanges have de-list procedure after a while a coin being listed but the other majority don't. Cryptocurrency exchange filed is juicy but since the related laws are missing, well reputed companies in stock market shrink. It's even difficult these days to find a good exchange to trade altcoins, aside from the decent exchange Binance.
