The point for understanding what would be profitable is related time span,
for sure now right now I will choose btc, that could become easily a "cubic gold" with a 5 digits value.
i will choose bitcoin too like you, i see that bitcoin have a good future and i think its good for to trying with bitcoin because bitcoin can be get for free and i don't have to spend my money, i can have it for free by doing anything. but for gold, i think i should buy it and for now, my money isn't enough to buy gold.
yeah bitcoin has a bright future so that bitcoin prices will definitely higher in the future. may be 2 or 3 times higher than current prices
