Now cryptocurrency market is very unpredictable. It is like a casino. You can win money but you also can lose it.
Many people lose money during the fall of the market.
But the fall gives people more abilities.
So it is necessary to check everything before investing not to lose money.
Well actually cryptocurrencies volatility and unpredictability didn't change after all since then and that's what I think the most efficient and consistent characteristics of cryptocurrency that a new trader who wants to join the community should learn first. Answering the concern of OP, for me if he see a good profit that he can earn in cryptocurrency well I will not going to question that because that is quite true but somehow it is risky and take time so patience is a virtue here.
