We have to thank jack Dorsey for being a true advocate for bitcoin, even more so than elon musk who hasn't done much in crypto. Square is a great app, this is good news
Not sure why you have to bring up Elon Musk? He hasn't ever expressed his interest in crypto other than a few Tweets people jump on like a bunch of hyenas and scream moon time afterwards. Elon Musk is busy doing other things, which actually improve the world and help potentially explore worlds outside our own.
Con artists like John McAfee haven't done much in crypto at all other than scam innocent people by promoting and pumping scams.
