It's funny because most of the people in bitcoin is just looking for the profits.
I doubt in the future that bitcoin will replace any major currency like the US Dollar but maybe in the future it will replace a poor country's currency.

You're right about paying people in bitcoin, why do you think Steam closed their way of paying with bitcoin? Because it was fluctuating too much to actually be a currency.
Why did Microsoft close their way of paying with bitcoin? Same reason.

The only reason Bitcoin rised was the hype around it and people seeing a shit ton of people making money.
It wasn't people who were in it for the technology and they suffered for trying to hold it for so long.
