Not sure that was the name, it was the time when everyone was looking for gold in rivers and mountains in the 1800s I believe, I might be wrong.

Some people had luck and got rich, and most people never find a pebble.

But, the companies that got REALLY rich, were those selling the equipment to look for gold. And I mean shovels and all kind of similar hardware back then.

What companies are investing not in Bitcoin, but in business related to Bitcoin?

Any tips on this?
