Kraken has always been a decently sized crypto exchange and place that people used. However it also got blasted by the SEC and the oppressive government to the point it was slowly killing the business.
Kraken currently holds around 42 billion dollars worth of crypto assets in it's wallets. Why on earth anyone would keep their funds on an exchange is beyond me but a lot do it! I guess since they feel it's a USA company that their assets are safe but they really are not and I think more people should be aware of that. Or maybe they are and they just don't care.
Part of the overhaul now that they are out of the SEC spotlight is to focus on expansion and that expansion seems to be coming in as futures trading offerings and margin trading. These are actully big moves as it gives traders more flexibility and higher leverage options with their crypto assets.
