Why do old exchanges continue to close such as cryptopia, coinexchange and the new nova exchange, what is the reason for the lack of users or teams that are no longer solid? but new exchanges continue to evolve but users are few and they last long.
Cryptopia closed down because they got hacked. The others however, I think the issue was too many coin wallets. If you have 10,000 coins listed, you have to pay for servers to keep those wallets going. If no one is trading them after a while, they're not worth keeping them going. Both Coinexchange and Novaexchange had a bunch of coins you've never even heard of with absolutely no volume on them that they had to pay to keep going. They both should have removed coins that were under a certain amount of volume and I think they would have been fine.
