Before you start buying or trading anything you should learn the basics first. Make sure you have the proper knowledge about cryptocurrencies and about the security that is needed for you not to lose your money. There's no point in becoming an expert trader and then losing your crypto because of inadequate security measures. For starters, all of the funds that you are not trading with, I suggest you take them to an external wallet and not keep them on exchanges. You probably have heard about Quadriga. All of the money people kept on that exchange is now lost. Don't make the same mistake. You can also invest in proper devices for your crypto devices, such as a cold storage hardware wallet, maybe a specialized offline computer to keep your funds, or even a smartphone that is specially created for cryptocurrencies, for example, the Wings WX phone by BitWings. Whatever you decide to do, remember that knowledge is key in starting with anything new.
