If you do not know the limits of risk with money, then in any case, you will not have enough money for a long time 
Just do not forget one simple thing, that not all people have enough patience to work with small amounts of money to earn as little money when there are a lot of stories about quick enrichment around. Therefore, we can talk as much as we like about limits and about some caution, but there will always be a temptation to risk a larger amount for the sake of getting more profit. Therefore, the absolute majority of people perfectly hear the voice of their reason, but unfortunately they do not always listen to this voice, hoping for a miracle.
That is the problem with all the traders, people fail to see the long term and that hurts them. I believe that I will retire when I am 40 years old, that is 10 years later and I know that crypto will help me do that so I am growing my portfolio as much as I can, mostly failing unfortunately these days but I am trying my best. This doesn't mean that I have to retire in 10 years, I just want that "option" and I could retire in 20 years when I am 50. That way I am leaving myself a huuuuuge long term goal and I do not have to make money right now right away asap, many people think that way and want to make some profit that way which hurts them a ton, because they want to get rich right now, but fail.
