Bitcoin seems like a huge Ponzi scheme, just with any other Ponzi scheme, its adopters fiercely fighting and trying to silence anyone who dares to utter anything opposing it. Bitcoin as it stands today has potential to destroy all the gains we have made in clean energy and bringing zero carbon offsets. Bill gates is right that it is massively inefficient in what is supposed to be doing. That is doing transactions. Just like previous bubble runs this Bitcoin bull run again will die down, with many of same people holding this worthless bag.
