To get a big profit from crypto investment, the most important thing is to dare to take decisions that may seem unpopular at the moment, most successful people don't care about what other people say and focus on their goals so that with clear focus and goals, we can get big profits.
You will think like that because you have not done all your funds to invest. i tried a sure faith and bought some nice coins but its going downhill at the moment. be something that really confuses you. Imagine you have a lot of funds and all invested ended in losses until now.
If you have bought some nice coins for real (and not shitcoins) you don't need to worry, because at some point crypto market will reach a new bull season, so they are going to pump again. Investments must be focused on long term, that may take years to return profit, just like people who bought bitcoin in 2017 when it was at its ATH and were only able to recover their investments 4 years later, in 2021, when bitcoin reached a new ATH.
