I have been been trading on ecoin for a long time and I must say that none of the currency pairs on forex can earn so much proit as 1 BTC can do. So this answers your question that bitcoin trading is the best option as it was not too far when the price was $250 in September-October and it is now $383 ($133 profit in just 2 months if a person bought just 1 BTC).
It's true. After spending years on the currency exchange i believe that BTC is by far the best commodity in terms of trading. A slight increase in value affects your holdings in a more significant way.
its difficult to say, which one is the best...
coz, it reflects on how paranoid you are... how accurate your prediction... and how high your success rate in paranoid-ing
