In the end we all are here for the money in some way. If anybody tells you that he is here for the tech, he is lying.
We know the tech behind btc is good, That's why we expect big returns for investing in it and I see nothing wrong with it.
It's a combination of tech and returns, but eventually the returns will no longer be there, regardless of how good Bitcoin's tech is. Bitcoin will grow so large, that it will most likely follow gold's path to become a slow moving asset.
At that point Bitcoin's currency aspect will finally be allowed to function as what it was intended to function as. The volatility is the main obstacle it has to overcome and once that is done, Bitcoin is literally the best form of money.
I however think we're still like 10 years away from seeing that scenario become reality. It won't be easy to shake off all the get rich quick speculators with how crypto is becoming more popular amongst them by the month.
