Should you hold your coins in a web-based wallet provided by an exchange, or your own  wallet? There’s no right answer for everyone, but it’s important to understand the trade-offs if you hold coins. Beacuse When you rely on an exchange, you have a more convenient experience. You don’t have to worry about securing, backing up, or otherwise managing your own wallet. The exchange’s website will be more secure than many people’s computers. However You’re placing a lot of trust in the exchange if you store your coins there. For example, you could lose your Bitcoin if the exchange were hacked, a rogue employee stole your private keys, or if the owners of the exchange took the money and ran.

It's better to save them in your wallet in pc better than exchange. Becoz exchange can scam but wallet will remain on and save your coins

I strongly recommend to only leave coins at the exchange during the period you want to get it traded. Aside this, I always and shall forever continues to leave my funds in my wallet wherever and whenever I acquired them in one way or the other. I believed the risk involved in leaving funds at exchanges is higher in terms of been hacked or scammed, since exchanges are one the most targeted areas for these ridiculous scammers and hackers.

I frequently heard of people getting hacked on exchanges but it's very rare on wallets. Scammers want to target an easy but with a huge money inside and people like us who only have a single btc is not worthy of their time so always leave your assets on your wallet.

According to me, it is safer and a way better option to keep your coins in wallets because Exchanges are always subject to hacking.

On exchanges, it is worth keeping only those coins that you trade every day or which you want to sell in the near future. If you bought something for a long time - it is better to withdraw to your wallet is not tied to the stock exchange.

It depends on your crypto strategy. If you are going to hold tokens there is no difference where to hold. But an exchange is more simple and useful. You can check your balance, price of tokens, buy or sell in one place.

I keep my investment all spread in different wallets and exchanges. There is no way to say what is safe. If you keep it all in the wallet then more or less you are yourself in control of them, but keep in mind that if you get hacked then nobody will help you. If you keep on exchange then they also have access to it, but if it gets hacked at least there is a hope that exchange support can help you. So the only advise I can give is not to keep everything in one place

In principle, not so many purses are needed, one for bitcoin, the second Etherium and for all other coins!
