The veteran people on crypto tend to say that you should keep your coins in your wallet, never on exchages. However if there is a strong downwards movement on a coin and you want to sell to buy latter at a cheaper price it may take quite a bit of time and fees to move it. What is the right strategy?
I think you need to plan ahead on when you will sell your coins. The transaction fees is not that high enough as compare to your amounts of your coins that might get loss at the exchanges. If you're a long term investor then you don't have problem about keeping your coins at your wallet.
