Is it safe to keep your all crypto currency at a single exchange (bitfinnix)?Or one should choose multiple exchanges.
depending on how long you will hold your coins, if only for the short term does not matter you save it in the exchanger, but if for the long term this is very dangerous, because it could be exposed to the hack or close the sudden then your money will be lost, save your coin in the wallet that you hold its private key
This is what i thought because saving longer time in exchange will be much more dangerous and suitable for long term holder.
Exchange wallet is just for day trade or short term who can really easy to sell their coin at anytime.
