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 never hold more than 200$ on exchanges. because i cannot trust them. we remember what happened for MTgox and other exchanges. so advise you trade in long time frame and withdraw your money from exchanges.
