Holding BTC was one of the few safe places to be today unless you care about $ values. Everything else is plummeting versus BTC so it is a great time to be buying alts unless you believe this drop is going to be followed by a massive BTC rally to the exclusion of alts. That does happen, but seems to happen after a first run up and people have already bought into the alts, then if BTC keeps going it cannibalizes the alts as everyone gets FOMO.

Yes, the futures contracts are expiring today so hopefully this is the end of the dive because I've spent most of my BTC reserves on great alt buys.
