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 cannt judge from one side to rate bitcoin. like you say "bitcoin like a lottery" maybe it yes cause the price is up and down. but its not only for price if you want to invest your money for bitcoin. for now so many market accept bitcoin for pay and its one of the reasons why so many people like bitcoin.
