Yes JJG you are absolutely right. Except for a very few guys, others will not be able to keep themselves confined to 10%. If they are lucky enough to make a good profit in Sitcoin once, they will not be able to control their greed later. They will keep looking for their luck again and again and will invest more than the profit they made and will keep losing money.
They will keep thinking that once they made less profit due to less investment, this time they will make more profit by investing more.
As a result, they will keep losing money.
That is, the previous luck will later turn into misfortune.
But those who can control this greed and hold themselves, then they can keep a very small amount of money in Sitcoin for experiments.
When I think deeply, it seems to me that Sitcoin is a real reservoir like a mirage, Bitcoin.
I am truly grateful to Bitcoin because it has been providing real principal in a good amount by protecting my money from losing value and will continue to do so in the future.
Many people don't know when to quit once they've earned a small profit, once they win small on shitcoin, they begin to believe they can do it again and again, instead of stepping back to enjoy the profit or investing in Bitcoin, they continue to put money in, believing they will gain more. But sometimes it ends in loss; greed starts to control them, and they continue to go after that first lucky win. This is how they lose all they've worked for.
However, if someone can manage their greed and only put a small amount to test or try something out, it isn't that bad. Even if something goes wrong, they will not be in too much pain. The problem starts when people go too deep, believing that their luck will continue. As you said, first luck can quickly turn into bad luck if one is not careful.
Sure, Bitcoin can help secure someone's money, but only if the person is consistent and understands how it works. It's not something that works with magic, but if we make use of the opportunity, it cannot just help us save our money, it also helps us to grow our money over the long time. It’s impressive to see how Bitcoin has benefited many individuals, including myself, by allowing us to grow little by little without losing money.
