The first thing to do is the introduction of cryptocurrencies because many newcomers enter because of the high Hype of Crypto so they hope to get a quick profit without doing a long process so knowledge of crypto is needed to see what risks we will get later when we start entering to trading in Crypto.
If I may suggest newbies they should before deciding to enter the world of crypto they need to prepare everything both knowledge, skills, and mentality,
it's not that easy to make a profit in crypto so all it takes a process,
if we don't have any preparation it's really very risky because we can lose money easily
