It is always better to keep money in different places. So I think it is good idea to organize wallets for every currency. On my mind it should be well-known reliable services. Then you will be sure about your savings.

of course I would advise you to keep all your investment in the wallet. which I use. for my ethereum using myetherwallet, and for bitcoin I use clear blockchain. but there is a end I more store all my inveatasi coins in exodus and coinomi walle

I am prefer exchange most. Most of the exchange have two factors authonication and mail verification for exchange security. I think exchange is more safe for coin or token hold.

Without a doubt, keep it in a wallet you control. Only keep bitcoin on an exchange while you’re trading. Only keep bitcoin on an exchange that you’re willing to gamble and lose. Only keep bitcoin on an exchange that you’re willing to see disappear if the exchange were to get hacked or vanish. The only safe place to store your bitcoin is in a wallet you control.

Do not store coins in an exchange if you are not going to trade it. There is a big chance for your coins to loss once the exchange is been hacked or having a big problem. Only put coins in exchange if you are going to trade it and withdraw it immediately in an external wallet that you hold the private keys once you are done trading.

everybody wants to keep their own tokens at the wallet but I don't want to pay exchanges withdrawal comission.But I use safe exchanges like bitter

Well this is not a fact that they are safe. how many times hacked exchanges and exchangers. And how many times did the money for them hang.

I prefer the wallet. This is a reliable storage of your funds for the long term. Exchanges tend to be closed..

For security reasons, you should keep your bitcoin on a flash drive with your wallet encrypted with a strong password. This prevents theft. Modern bitcoin theft involves inside jobs like an employee just transferring the bitcoin wallet on the exchange to a laundering service. Another form of theft is the exchange being subject to a hacking attempt which succeeds. The attacker then sends the exchange’s wallet to a laundering wallet. In the end, you would have to lawyer up and likely lose most of your bitcoin in the end. Having it encrypted on your own flash drive avoids trusting the world with your bitcoin.

exchange sites are better to make transactions quicker and take advantage of instant fluctuations. But from a security standpoint it seems much more accurate to keep it in your own wallet.
