Re: Gold rush...
In any "gold rush" an infinitesimal number of people become very rich, a small number of people become well off or rich, and the vast majority lose money. Most of those having come late to the party, whether it was after tulips or bitcoin had already doubled in value a couple dozen times, or after all the places with gold easily pannable from the stream had been claimed and picked clean.
How do you know if you are "late to the party"? If you heard about it on the news, you are too late.
