I do think you are right about that. If we lose all our investment and capital we can still invest again. We just need to be more careful so we will not lose more of our capital.
There is alot of traders that does lose all of their capital. But for crypto investing there is alot of coins we can invest in. So if you don't run our of capital well then you can still make profit.
All traders do have to fail for some time. It is just how it is when you are a investor in crypto. But some of them do make alot of profit after failure.
That is only if we have more money. But if we invest because of greed and lose all of the capital, we can not start over. We will regret what we have done. Many people fail when trading but not many of them can search for their mistakes and fix it. Losing in trading can happen anytime but if we can know the mistake and fix it, we will have an experience and will not make the same mistake. So trading will need skills to analyze the market and only with learning more will help you to have better skills.
