I have a main job, a family and two children. All my free time is spent on them. I spend a little on cryptocurrencies.
To earn in some industry you need to spend time on training and familiarization. Without studying the cryptocurrency market, you will not be able to earn good money.
You are right in saying that it is necessary to study the industry which you want to deal with. I spend enough time studying projects that are promising for investment. But my family is most important to me, so my first time is family time.
Family should be the most inmortant thing in the world. If you have it for sure.
But using risky things such cryptotrading you should be 100% right with your movements there. It is very easy to lost everything in a one day if you do not have a trading strategy.
