I have had ADA for about 6 months
But it has not yet become profitable
I like to focus more on new coins
This sounds more like you are looking for some gambling instead of doing a serious (long-term) investment. 6 months isn't a very long time. There will always be cryptos (or other assets) that will outperform you, but it's not always worthy to run after all possibilites. Do your research and focus on a small number of projects
