some of my coins put on the exchange and some of the others I put in the wallet. my reason is because the exchange sometimes closes. and in the wallet sometimes there are hackers who want to steal my coins. when the exchange is closed maih there is the rest of the coin in the wallet and when the coin is missing the wallet there is still a coin on the exchange. it's my strategy to keep the coins I have

i prefer wallet. You should decide by yourself according , A large many coins are better to put in a purse. It's more secure.

It is far better to keep your coins on your personal wallet than on exchange. Anything could happen to an exchange it may be hacked or disappear but your wallet is always with you.

right, you should save your assets in a private wallet before you decide to sell it. i think it will be safer, given the many hackers who tried to break into the exchange, and suppose you want to save in exchange better keep on some exchange to make it more secure

Exchange is good but Wallet is more safe as Exchange. wallet with private key for coins that you dedicate hold for long term investment. Remember not all of the wallets are fully secure too.

i cannot exactly tell which is better, exchange or own wallet, im holding my coins on both - exchange,in my case this is binance, and wallet - metamask. Sometimes needs to buy something fast on exchange and not to lose time for transactions

Wallets are the best for storekeeping your coins. It always was. Although you can always immediately trade your coins if it is stored in exchanges, but the security risk is much higher than when it is stored in your own wallet.

I think getting your coins in a reliable wallet is the wisest thing to do. Note, in keeping those coins, one has to sure of its security authenticity of any wallet to be used, hence hackers and scammers will eventually feast on those hard earned coins.

Cold wallets are the most safety now. Exchanges have many vulnerabilities and can be easily hacked. Moreover, centralized exchanges just can disappear with your money without a trace.
