If the price doesn't go up on Beam coin, Its not going to be worth mining anymore. I think in an effort to exclude ASIC's, somebody forgot about the HUGE GPU farms out there.
Thats the problem with BEAM and GR** too. Everyone sells their coins at the lowest possible price without using just 1 cell of their brains, no matter the exchange rate. Instead of selling in chunks, each chunk with an increased price. Yes, it need some minutes to sell. But you get much better prices and the coin value increase, not decrease... Win/win for everyone!
Today its not worth to mine BEAM anymore and this is so sad.
