Among the crypto exchanges that support multiple crypto assets, one cannot easily shove off Cryptopia. It is an exchange with above 400 crypto assets including major cryptocurrencies, stblecoins and lots of altcoins. It is based in New Zealand.
The exchange was widely adopted. It had millions of traders and a very large social Media community on Twitter. All was going fine until it was hacked and wrecked a colossal damage in 2019. Since then the exchange has been offline and liquidators has been appointed.
