After a few months I got better at trading. I was earning more Bitcoin than I needed to cover my monthly expenses. At the end of the month I sold only what I needed, and kept the rest of my net worth in Bitcoin. Around this time in my trading career it was getting to the point where I could have bought a Tesla or put a down payment on a house by selling my Bitcoin.
Knowing generally how people are behaving, how they are feeling about the coin’s activity, and the news flow (i.e. government, or big business factual news about the space) surrounding the upturn or downturn that will push it one way or the other is the key to this strategy for the trading of cryptocurrency.  One can’t really tell exactly but using the right clues we can make smart decisions based on the preponderance of the evidence.
UPDATE: I do not recommend paying to enter a Cryptocurrency mastermind group – I’ve tried a few and found the ROI to be disappointing. I am now focussing on growing my portfolio passively utilising a cryptocurrency trading bot, the renowned Notorious Bot. Having a bot that trades for me, without emotion, using an advanced algorithm, allows me to grow my portfolio in the background without it cutting into my time or stressing me out. You can familiarise yourself with the basics of cryptocurrency trading bots here. 
I’m not going to go too deep into other ways you can earn money with cryptocurrencies because I don’t do them myself. At least not right now. Passive income is great. After you make an initial investment, you mostly sit back and watch the money roll in. It’s like buying a home and renting it out - there will be some maintenance issues but it’s mostly passive income.
Don’t invest blindy. There are people in this world who would sell a blind person a pair of glasses if they could make money. Those same people play in the cryptocurrency markets and use every opportunity to exploit less-informed investors. They’ll tell you what to buy or claim certain coins will moon, just to increase the prices so they can exit. Due to the highly speculative nature of the cryptocurrency markets today, a good investor will always do his or her own research in order to take full responsibility for the potential investment outcome. Information coming from even the best investor is, at best, great information, but never a promise, so you can still get burned.
