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?
The fee is always included when you are into crypto currency. You just need to keep your coin in your own wallet for a security reason, exchange is vulnerable in hacking thats why beterans dont want you to do that. Just send the amount you want to sell in time you need it in exchange thats the best strategy you should do. before you stored it in exchange always remember what happen in mt.goax.
