Is it safe to keep your all crypto currency at a single exchange (bitfinnix)?Or one should choose multiple exchanges.
Storing your stash of cryptos on an exchange is not even recommended in the first place. Only do so If you're an active trader and only keep a percentage of your holdings on the exchange. While dealing with Cryptocurrencies is interesting, one major downside is the security. In just one clean swoop, you can lose everything (Your profits, capital) etc. You've to take it seriously so. Just get a personal wallet instead.
Even for active traders using 1 trade exchange will be quite risky, I myself use 3 exchanges for variety and security, it will be much
safer and more profitable than just using 1 exchange. other than that if you want to save long term, then choose a wallet.
. Now there are several thousand different tokens and cryptocurrencies and it is absolutely unrealistic to have them all on one exchange. The software of any exchange will not be able to support trading operations with such a number of cryptocurrencies.
