Bitcoin is a pyramid scheme of passing the hot potato, which has long been banned by the state. This thing has no credit endorsement and is not legal tender; the central bank strictly prohibits financial institutions from participating. Although I bought some in the past, I am fortunate to have realized and sold all of it early; not only did I not make a profit, but I also lost a bit. I advise you not to touch it either; don’t be foolishly handing it over to the Americans, as that thing is designed to trap Chinese people.
