I dont think having your cryptos in an exchange is any safe. Better to have it in your own wallet. Exchanges are exposed to being hacked.

There is a lot of difference between the  Exchange or Wallet.Wallet works like a bank account and works like a exchange market. Where you can sell and buy other coins with Etherium. If you want to sell tom token, use the  Exchange and Wallet to keep the token. So many of the importance of  Exchange and Wallet.

I think you should store your assets in exchanger. Why?
Because there will be a moment, that you will heard an early hot good news of an coin, before the coin goes up, you can directly buy some for short profit.
I'm doing this trick. just follow the social media of some bitcoin news account and crypto experts account

Its never been safe to hold your coins in exchage. Paper wallets are always safe then exchange wallets.
I prefer to use paper wallets for long term investments. and i use metamask for daily used wallets.

You better keep it in the wallet, because when you want to move your coin to another wallet in exchange will be charged more expensive. There are many other reasons why you should choose to keep it in the wallet.

You may know that online money store Myetherwallet is used to store Ethereum copper, BlockChain used to store Bitcoin copper and Exodus used to store more than 15 different types of coin. These e-wallets are now very popular and give the investor a lot of benefits. However, the risk of hackers, trading floors collapsed or the online store hoard is disabled appear more and more. And then the property stored in online wallets of investors will no longer be protected. As the risks appear more and more, there will always be solutions developed to bring about balance. Investors will be looking for a way to stock their coin as an asset. And an application for the implementation of copper coin stock solutions was launched so investors could stockpile money as well as prevent the risk from happening to them, such as cold storage of electricity bills. death Cold wallets are used in non-internet environments, which is why you should use it!

This is a complex issue. On the one hand, the wallet is more reliable. After all, only you have a private key from it.
On the other hand, the private key does not guarantee you 100 percent privacy.
Even if you keep your tokens on the exchange, you still specify a private key from the wallet.

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.

So far I only keep altcoins in some exchanges and for btc I save on web wallet and some in exchange too. So far I have not had any problems there, but I once had a problem with poloniex because I could not withdraw funds, but it was already resolved and I left polonix now to prevent similar things from happening.

I think all depends on how much coins you have, if you have in 1 coin more than 1k$ then its better to send to wallet, if less than all in exchange.
