Anyone knows why bitcoin is going up and the alts are going down? Usually they go together. Progress in the LN tests perhaps?
They don't always go together. Sometimes money flows to Bitcoin out of alts, sometimes money flows into alts out of bitcoin, sometimes money just flows in to everything or out of everything.
Right now money is going into Bitcoin because there is more and more talk from institutional investors about getting in fairly soon and there is another chance at Wall St's first Bitcoin ETF getting approval next month. There is also a growing thought that the bears have finally been beat and we could be at the very start of the next bull market, which means smart money is getting in this summer in order to make loads of money the next year or two. ETFs alone over the next bull run of let's say two years could be worth tens of thousands of dollars added onto Bitcoin's price.
