You have already started trading, but yo do not know where to store your bitcoins and eth's.
I dared to start trading , I have enough funds to purchase BTC or ETH, but I don't know, where to create wallets and how to manage them (I mean safety issues)?
Security is the first thing that you need to think about before trading, and let me tell you that if you are going to put all your money on trading, or if you are going to be the whole day trading, the best thing that you can do is just move all your funds to your exchange.
Maybe it is not the best thing that you can do, but you will not spend more than five bucks everytime that you want to move your $ from there.
