Some people like the Brazil Central Bank Chief called Bitcoin a Bubble & Pyramid Scheme, how can the bitcoin industry prove this wrong and make sure bitcoin never ends but grows bigger?
To be honest, no one in this world can do anything to assure you that bitcoin or the whole cryoto world will never ever end. That's just how it is.
Bitcoin does not need to prove anything that it has already proven. Let them talk and talk about all sorts of bullshit asich as they want. They will be the ones stressed out while we, the crypto people enjoy the perks of being in the crypto world laughing at their insecured and jealous faces.
So don't be so worried about them. They don't matter. What matters is what we do.
