I did not realize that alts had a good week, specially ETH, when I look at it, it doesn't look in green for the past seven days, but maybe I took the wrong period to calculate. All in all, domination changes during these times, and I can guarantee you, there will be a period when bitcoin will go up al to more than alts during this period, it will not be all that easy and people will lose a lot of profit chances if they do not switch to bitcoin. Why? Because during the bull run, first bitcoin goes up, and it goes up as much as it can, then it can't anymore, so people take their profit and start putting their profit into altcoins to make money from that.
