Of course, it's not recommended to hold or store your coin/tokens on the exchanges for a long time
better to store it in the wallet, it's more safe.
Right.That's why we have our own wallet with own private keys so we can keep it safely and privately away from hackers around.There are a lot of negative news spreading about some of the exchanges being hacked even those who are trusted by most people.So we should think of the safetiness first of our hard-earned coins than letting other people benefit from it.
