Everyone has the right to speak anything but everyone has the right not to believe. I am one who has not believed if Bitcoin will go to Zero or worthless. This is because I have gone through several years of betting and Bitcoin can always work better than anything else.
In addition crypto and digital currencies are the future. Nowadays all are turning to digital. Even the state has studied, and they have created their own digital currency. Sometimes people who say bad are just a strategy to make a profit. So I will remain calm and keep trying to improve my BTC.
