Okay, enough with the early-bird vs. second-round "investors".

I am one of the early-birds and don't care if BTC has become 50% less valuable.
Would you also complain if BTC had risen to $1400 and second-stagers had to pay double (in fiat!) for a stake?

Stop being so selfish.

It's a stake in BTC, so stop converting to fiat. BTC = BTC.
Tough luck and shit happens
