. I think i prefer to keep your coins in any secure wallets instead on exchange site, ' to make sure that your coins is in a safe place.  'cause honestly we are not sure if the exchange site will stay forever and to be honest there are some exchange site that suddenly disappear after a months  . So i think the good idea is to keep it in any secure wallets to prevent regrets. 

I would put my coins in wallet becuase its more secured and you have the control of your fund while on the exchange you dont control your private keys.

Everyone who keep their funds in an exchange will always learn the hardest way if something happens to the exchange. Y'all should ask those who have been a victim of not having their funds in a wallet they have the private keys. Always consider the safety of your assets first before anything else. That would make you stay richer.

I think exchenger is better then the wallet for keep coin. It is more safe to hold coin from the hacker. I have lost my some coin for keeping wallet. Then I use to keep or hold coin in exchenger. Hope you will helped.

The point is not that the vulnerability exists in the event that the exchange can hack. The fact is that it is not safe to store the cryptocurrency on the exchange because there are cases when the exchanges were just closed and took away all the savings with them.

I'm long term guy and prefer wallets. I'm still holding some coins on the exchanges but most of the my protfolio in my private wallets.
But it is bad to miss some big opportunities sometimes

People are always paranoid about holding on exchanges, but i have 6 different exchanges i hold on and i doubt all 6 will get hacked. So even if i were to lose one exchange it wouldn't be the end of the world for me. I did lose some coins on coinsmarkets when they faked having server troubles and supposedly temporarily closed but than never re-opened stealing everyones coins in the process. So it has it's risks.

If for keeping it is better to use wallets, It is safer because you're the only one who have access to your coins. Just make sure you keep all your details confidential.

Unlike exchanges, admins of those sites have access to your account even if they say that they'll keep it confidential. One "troubled" admin of the site can ruin everything, not just your coins but the whole reputation of that site.

Do not store many currencies on the stock exchange. Leave there only the part with which you are ready to part. Already there were so many cases of different hacker attacks. From this no one is immune. Be vigilant and divide coins even into different wallets, except for the stock exchange purse. Keep it altogether separately.

if only trading is good use exchanger wallet
but if hold longterm or collect coin from bounty is good use official wallet, sam Ple if ETH can use deksto P wallet or myetherwallet
