I see this post all the time, people who keep saying that bitcoin will soon disappear or we are about to see the end of bitcoin. I read somewhere that the price of bitcoin this year is not the lowest since bitcoin's inception. It has dipped lower before, if I remember correctly, it was 80% drop. With that in mind, how could people say that bitcoin is about to cease existence? If it can survive an 80% drop, surely it can survive the drop this year, right?
Just let them think what they want to think. Don't bother them. Even how good and properly you will explained them those "things" why crypto won't disappear, they will stick to their stand that bitcoin or basically all cryptos are bound to end.
Remember that you have lots of reasons to believed that crypto especially bitcoin won't die. Not just a pure speculation and hype but we have a real and technical outlook for that and it will required long writing if we will explained each briefly.
Stay positive. Surely everyone's expectation to bitcoin will happened soon.
