Exchangers are not wallets, there are many exchangers that were been hacked by the hackers. You can ensure that your coins are safe if you will keep it in trusted wallets.

An exchange is where you buy/sell cryptocurrencies. A wallet is where you keep cryptocurrencies you’ve bought or have received. they are different, you must know what you want to do, we would tell you some advice.

my advice is keep on exchange only the bare minimum and only for the time of the transactions/trading and then withdraw to a personal wallet of which you have private keys

Exchanges are mostly used for trading because all coins are not listed on all exchanges and if your horizon is short term then you can hold your coins in any online exchange which have your coins but if your horizon of investment is for 2 to 3 years then you can hold your coins in online or offline wallet as per your wish. Trezor and ledger nano is best wallet to hold coins for a bigger term as it is not accessible without connecting it to a device.

Is not that still Clear for you being a Full Member and being in crypto for at least half a year? Remember one simple thing - once you deposit your money on exchange you do not own your money! I am having official wallets for coins that my Ledger nano s does not support, as for exchanges I only deposit when I want buy to sell smth and withdraw from it immediately. Is not MtGox and other exchanges do not teach you anything guys?

Why you do not own your money what put it on exchange? Thank you so much for warning, I had no idea about it! Now I know

because in the case of the "benches" of the exchange, all the wallets will remain with the owners. And since they have all the passwords then your funds will actually belong to them

Wallet of course. If your fund is held in the wallet, you have total control and you can have a rest of mind.

Im holding my crypto assets on both platform. I have crypto in my wallet for long term holdings. I have also crypto in different exchange for daily trading. Being there saves my from transaction fees from transferring my crypto back and forth.
