Actually, if we talk about investing in Cryptocurrencies, this is difficult to explain. Because we all know that Crypto has a lot of choices, some are fast and some are slow. 
For example, we invest $1000 in 1 Crypto Coin, in 1 month the value can increase 10x or even 100x if we happen to choose a coin which at that time the coin experienced a sharp increase, but it's difficult. 
Determining which Crypto option we choose is the difficult one. But at least we have the courage to make a choice, but we also have to remember about the big risk here. 
So we have to be careful, we ourselves must be responsible with our money.  Don't lose it all!
