can you use an asic miner like the ant miner l3 to mine Belacoin
Anything that allows scrypt mining.
Bela is a ltc fork so anything that can mine ltc can mine bela too.
Afaik L3 is a scrypt miner, so yes.
I'm mining with AMD 470, so what program could i use to mine except for both cudaminer and ccminer?
Much thanks
SGminer and GUIminer. Should be others too - just google for 'gpu scrypt miner'.
Cudaminer is for Nvidea gpus so it might not work with your AMD gpu.
