Never buy what you do not understand
The CEO of Binance gave a great interview during which he
advised all newcomers to better study the industry and avoid investing large amounts in the initial stages.
CZ also warned against investing in assets
one doesn't know and to avoid "falling for big, familiar names":
"Get to know the industry, beware of assets whose names seem familiar (actors, companies). If you don't understand even BTC, don't buy it, study it first. Cryptocurrency quotes are subject to high volatility, no one controls them. The basic and simple rule is: don't buy what you don't understand".
