Hmm, low startup 100%-1000% profit margins(if you started by early may) compared to high trading startup fiat currency markets ?
This is more fun, more profitable with low startup funds(big margins on trades), damn its so obvious why this is worth doing. I dont say if you succesfully trade other markets that you should invest all your time in bitcoins however investing a few hours a day can bring you alot of profit for very little stress.
