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?
Actually, yes we don't need Bitcoin but if you are broke and needs an extra income, you need this investment to gain money. Yes you are right about those people who is influencing new comers and beginners to sell all that they have in order to buy Bitcoin. I think they should just treat Bitcoin as a side line job for them to earn a bit of extra money to support them to a certain need. They should just put a little investment and see what they can get, after all Bitcoin has already gave a lot of people profit.
