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?
Yeah, bitcoin may has lots of benefits that we can get from it. So not at all when no one can know clearly about it and can't hold its value( its price). And that's really not a good idea when leave job or sell house to invest into bitcoin.
