But instead it turned into a game of "hodl" to get rich.
Scams were openly perpetrated in the forums.
I became completely disillusioned. What exactly does bitcoin offer the world today?
Aside from perhaps gold, bitcoin is the most successful currency in the world not associated with a central bank and state.
It's the most liquid asset that is not issued by a central bank. At any point you can issue a transaction to anyone else in the world, without the possibility of a third party intervention. I've had issues pulling cash out of banks, or limited sizes available for money orders, or having debt/credit card transactions incorrectly flagged as fraudulent and blocked.
The now much more diverse mining space is much better than completely centralized in one entity current system.
And bitcoin community has a way of working to fix weaknesses wherever they find it... there is active campaigns to diversify mining, as you pointed out those are pools-- and pools are being made obsolete. behind those pools are thousands or tens of thousands of mining operators, of all sizes, as it's viable at industrial as well as individual scale-- many use it to heat their house for less than the alternative, the earnings don't have to cover the full cost to be beneficial to people.
