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.
So in essence, to be used as an active trade and or to save for the long term or to be used as a wallet, the exchange is not suitable to be used as a wallet and you must use more than one exchange for active trading. I once made exchanges as a wallet, and in the end I lost all the coins I kept there, if you want to find a wallet for crypto, look for a wallet that you can fully control or control as you can store and have a private key, and do not make an exchange becomes a wallet, because it is not recommended.
