Recently, they finally dumped their alts, which they were holding in hopes of a pump to make more bitcoin with, and simply held BTC. They have dodged the massive alt crash that has brought up BTC back above %50 of the crypto marketcap dominance.
Im not saying all altcoins are shit, but most are. It seems finally reality is kicking in amongst noobs that thought they could get easily rich with altcoins, and they are finally going back to BTC.
OMG. I am glad I am not your friend. would be such a loss to sell my alts now and not few months ago when was expensive. I think your fiends just distributed some of their value to the more patient ones
