Bitcoin and other cryptos have shown the world an easy way to make money practically out of thin air.
This lead to increased interest, and too many people rushed to join this craziness. Some of them made a fortune, most of the others simply lost their money.

The situation was similar during the gold rush. Some diggers found gold, most of the others left with nothing.
Shops, taverns and brothels made the biggest money in that period.

The same principle applies to the current situation. The best way to make money on the overheated market is to provide this market with what it needs most.
I'm involved into blockchain industry as a marketing specialist and this is one of the most reliable ways to make money here.
