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.
