On the exchange it is worth keeping only the money that you use for constant trading. At me the sum used for an exchange it only 20% from all volume as the most of money waits bulls, and there is no smsla them to touch in general. If you keep more money on the exchange, you risk becoming a victim of hackers.

if you want to hodl your funds then you should have to use your own wallet for safety. and if you want to trade then you have to use exchanges because there is no alternative. its simple. personally I use exchange wallet because I'm a trader.

if you hold on mid term or want to trade you can keep your coin on exchanger

but if you want to hold it as a long term investment, you better choose wallet to store your coin.
cause exchanger sometimes can be hacked and your investment gonna gone too.

both of them have their own risk. if you forget the private key in your wallet then your coins/token is gone too.

so if you store it at the wallet, just make sure you backup your wallet/Private key and keep them secure.

I like keeping my coins in a well secured wallet of mine. I remember I was used to keeping a lot of my coins at an exchange site and could you believe that was hacked. All the coins I have toiled for were stolen. I learnt a lesson from that and decided not to be keeping coins at an exchange.
I also fear that the exchange system may be interrupted which can greatly affect me.

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

Exchager wallet is not safe. If need to hold coin. You the wall it safe for your coin. But you not some information to other people. It safe for your wallet. If want exchange you charge the wall to exchange wallet. But if change the coin. You know the process before use. It any time to change the price. So check the price day by day. Then you get some ideas.

in my opinion each method has it advantages and disadvantages, so you shoyld think what will be better for yoh personally, good luck

To save your fund you should always put them in a wallet. Exchanges are only for trading. Do your trades then send directly to wallet.

For this, ill settle for wallet, Exchange is only suitable for traders. There has been continuous reports of exchange hacks where a number of coins were lost costing millions of Dollars, storing coins in an exchange wallet is not a risk worth taking at all especially if you are not constantly trading, Private wallets are safer as you are able to encrypt them to your own specifications and liking. With the invention of the hardware wallets, like Ledger Nano S, the safety of your coins is as good as guaranteed.

The best wallet address to save your token is the one you create by your self, because you have the full access to it, including private key, secondly any exchange used to sell, is a personal choice, than exchange wallet address.
