...Do not stake your all! ...
There is a rule that all investors must strictly follow: "Don’t put all your eggs in one basket". Of course, if fortune favors you, you can make a big profit, but you should not play roulette with her. The risks in any business should be adequate and in case of failure it should not lead to bankruptcy.
Therefore from that failure we can try again to become bankrupt, so it's true don't put all assets in one coin when one coin fails there are still other coins that can generate profits.
Sometimes there are still people putting all assets in one coin with the desire to multiply, Yeah if it's lucky what if not? That's what should be thought about not about profit but how to deal with risk when it occurs.
Diversification is better, because some professional investors do that strategy so that they don't go bankrupt, so I myself do it.
