Well , without a risk there is no profit :), i am not going all in, just using some spare money, and will see how it goes. And even if after 100 k $ i will be able to withdraw at least one day interest i will be making 2x more than i invested :) And the minimum is 100 $ It is not so much money. Its just a risk, as big as any getting profit from bitcoin, as it price determine by the demand for it :)

Yeah, that's probably the best way to look at it... Hope the best for you.
Keep us posted on how it goes.
