There isn't anything new, it has been since the inception of cryptocurrency and the best strategy I know so far and which I think is the best all time is to do long term investment rather than rushing, doing day trading or panic selling. To become millionaire in crypto you have to take your time relax watch the market for a long term and leave your investment to grow and appreciate overtime
The trend now is upwards for both the investment ratio and the price. People are investing in bitcoin because more and more people are investing in bitcoin to earn more and more money in the near future. So I think that people realized the importance of bitcoin and the price as well, therefore they are investing in bitcoin to secure their future.
