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 are right bro, we do not really need btc in life but it only happens that cryptocurrency is the easiest way to become wealthy and that is the reason why there are a lot of investors in this community because they are all hoping to earn a lot of profit in the future when the value of bitcoins increase at the highest price it can be in the market.
