I have been folowing Gramatik since 2010 or something also with his previous label Preety lights and knew the guy is into BTC ie he made the famosu song about Satoshi..
Lately he had a huge concert and put HODL sign on his back.
And today Lil Nas X put up a cool video and track about altcoins and bitcoin.
So play the music and trade as we had nice dump on BTC.
