Investing without learning, stupid thing to do. They just think of earning and double or triple their money, they don't think the high volatility rate of Bitcoin. Patience is the Key.
For bitcoin of course there is no doubt if newbies practice by investing directly. investment without analysis is gambling, crypto is a real project but many are scams, study in detail the team composition, if in doubt then ask a trusted source, especially in this forum, if convinced then invest immediately.
