Alas, those times are gone. In fact it’s getting much harder to make $1 million legitimately as so many crooks have entered the arena and investors have become leary after being ripped off by pump and dumps, ICO’s etc..
With that said, it’s still possible to become a millionaire with cryptocurrencies and here is the strategy:
Start with $10,000. Achieve an annual return of 100% (not hard to do in crypto). Do it 7 times and you are a millionaire.
Now imagine, if instead of one year, you can get 100% in a month. Do it seven times and in 7 months you are a millionaire.
How to get 100%? Learn to read a chart. I have found that when a coins price is well below the lower band in a Bollinger Band chart (20,10), it rises. You can easily get 10%. Do it 10x during the year and you have your 100%.
