We don't really need BTC. I hate when I see people trying to convince others to sell everything they have to buy BTC, it's disgusting. Bitcoin is a lottery, you shouldn't use the money you need to pay your bills and buy food to bet in the lottery right? Bitcoin is kinda the same thing. People should invest money that in case they lost it wouldn't be a big deal you know? It's a long-term investment, however, it's a bet. You can win a lot or you can lose a lot too. Are you brave enough to deal with this risk?
You really have a point in there. We actually don't really need bitcoin. Everything in business takes a risk, so as bitcoin. In investing bitcoin, you really need patience in it to earn more profits. The main goal of bitcoin is like a savings for the future.
