For me if you don't need to trade your coin better to keep it in wallet it is much safer than it is in exchange. but if you are doing day trading I suggest to keep on exchanges to save gas fee when transferring from wallet to exchange if your coins is in your wallet. 2 or 3 wallet maybe for all of your coins not making each coins a wallet though it is much safer but it looks confusing to me when you have a lot of coins.

For me personally I prefer to the wallet site of the coin than the exchanger site, and I think it's more safer than on the exchanger site.
One of my friends who used the wallet at the exchanger site was already being hacked, ever since I knew that.. I so avoided the exchanger site to save my coins especially bitcoin.

I keep a large sum on Kucoin. Since from this I receive a part from the coins sold at the exchange.Is it good & profitable? Yes, it is profitable. Is it safe? No, definitely, it's not safe. Since vulnerabilities are found every day and hackers work without closing their eyes. In the hardware purse, in any case, should be the investment that you value and do not intend to sell in the near future.

Since I am not a trader I keep all my coins/tokens on wallets that I have full control of course because I felt relieved once I know all my funds are in a safe place. Keeping and hodling funds on exchanges is just like you are giving them a chance to have it and take note it is not just a chance because based on my friends experiences their funds were stolen and some other exchanges issues occur during withdrawal so I think everyone should be cautious about storing coins/tokens on exchanges. Only store funds when you are planning to sell it so that risk is lower. Regarding wallets, the only thing that is a problem is when the time you forgot and lost your private keys so better keep those keys in a safe fireproof, waterproof and weatherproof invironment to ensure it will still be okay when you need it. Hardware wallets are good too but I think it is a bit pricey.

a wallet fir sure! though make sure its safe and secure !!

if you want to save in the long term, you have to wear wallet, if you keep it in exchange I am afraid to happen if the exchange is closed or scam you will regret lose your money

Yes you are right exchange was good to investing and trading but as you said that have own wallet and that was the storage of your coins that you earning in investment and trading so what is the difference between of that. I think even thou you are storing your coins in wallet that was also earning because the value was not stable and anytime it change so you are also investing if I'm not mistaken.

I don't think it is a good idea to keep any funds you don't need for daily use in exchange. Exchange is for trading, wallet is for storing, in my opinion.

The answer for your question should be overwhelming and that should be "personal wallets". Never ever leave your coins for a long span of time in an exchange. By doing that, you are just risking your coins to be stuck with that exchange when the company managing them goes south. You can sift through the history of cryptosphere and you'll be able to sight several instance where exchanges closed its doors to the public together with the coins deposited in them. Some of them turned into scam and some of them get "hacked".

The only way for you to take care of your coin is to store in a personal wallet (downloaded into your desktop/laptop) or by buying hardware wallets. You have the sole control over your coins if you do this and that's what you want to do in the first place. Never entrust your coin to anyone, not even in exchanges.
