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.
I like this one, "don't be so worried about them. They don't matter. What matters is what we do." This is true, as long as i am doing the right thing, i am earning, whatever other may tell about bitcoin doesn't matter anymore. I will do what is important for my future. They can't help me to have a better future but i can help myselp to have a better one.
