Beam.I think that Beam is a good coin that has a chance to get massive use and be popular in the future.
I don't know what chanses Beam coin has but I highly believe OP isn't someone who is looking for support Beam network, it's not very profitable to mine with his GPU. Currently best option is Aeternity but personally I would mine with nicehash because difference between these two is very low and I would try to keep bitcoins and wait for it's rise.
He can mine other coin and buy beam too.
