Let him sell if he wants to sell. He's been doing that if I can remember, so why worry if he's about to sell a bunch of bitcoin?
But he is lying. How can he have that many bitcoin? I'm just worried people believe it and the price stays down. I have bought bitcoin because it is digital gold so I don't want the price going down.
That's it, let him sell if he really has it. All of us doesn't want to see bitcoin's price go down but considering on how normal it is if we see it go down, it will happen eventually.
Don't think that much about him, he's just telling a fairytale and he wants people to check out his BSV. Do you really believe that it's possible to him to cash out that big money at instant?
