Well, when you want to start trading, then the first thing that must be done is to learn and get to know more about crypto and its development. Furthermore, for the start of safe trading, it will be better if you choose top coins that have proven to have good, high volume trading, and trust from good traders and investors. Start from the capital that is not too much and does diversification for a few coins. So, don't just pile up your money on one coin. And of course, you must be smart in choosing a trusted exchange. It could be that you choose a local exchange in your country that is already trusted or an outside exchange that is indeed good.
