At first I did not really understand what bitcoin was, but the passage of time that initially did not understand to be understood and turned out to produce more income.

Yes. I think that most of us have passed through the same experience as you, were we didn't understand much about Bitcoin and other cryptocurrencies to make a nice income out of it. But as time goes by, we mature and make better use of these innovative technologies to help build a steady income stream that would help preserve our financial future.
As for me, I went from earning nothing at faucets, to building my income with cloud mining, staking coins, and participating in the signature campaign. By investing the earned Bitcoins into something that would generate me more coins, it has helped me build a side income that has ensured my financial stability.
Nevertheless, the experiences learned with Bitcoin are very valuable and will help you make better use of it, as well as to teach others who are new into this field. The best way to learn by experience, is the hard way by losing some of your Bitcoins when getting scammed, among others. Just my opinion.
