Well, op you don't need to give up but you have to carefully reexamine what you have been doing and failing, this time do something different and right. You cannot keep doing same thing same way and expect a different result.
Pause!
Learn!
Restart!
Let me take trading as an example. Someone learn, trade and lose. Learn the more, trade and lose the more. Months after months become years and the trader continue to lose. Then if such person stop, there should not be anything like learning again and restart, he should just quit and focus on less risky means of earning. I understood you though and you are not wrong but there are sometimes that you just have to quit.
It's fine not to invest in cryptocurrencies, but it's wrong not to have cryptocurrency in this day and age. Investing in crypto is similar to gambling in that there are only two possible outcomes: it can make you rich or it can wreck your life.
It is like gambling if invesin in altcoins which can become shitcoins or dead, it is not gambling if hodling bitcoin. One of the main reasons to hold bitcoin is to be an hedge against inflation rather than having fiat in banks, especially in developing and underdeveloped countries whe developed countries are no left out because their local currencies still suffer declination, but even if the price of bitcoin decrease today, let us still expect all-time-high later.
