If you look it that way sure but future is unpredictible, its possible that btc will be 50k and also possible that year from now it will be 3k. Its also possible that this coin will be under 1 cent.. all is possible.. so i must look what is most profitable now and from my calculations nicehash is 35% more profitable.. also 2000 miners left suprnova rvn
Bitcoin has reached it's peak. RavenCoin is still ramping up. I'd rather risk my time on something that has room to improve rather than a coin that is stagnating and dropping. I don't need extra money, my real job pays me well. RavenCoin is an investment in the future.
