In the long run I don't think a ratio of 60+k invested vs. below-10k gambled is sustainable, but I guess that's a self-correcting problem
10k / 60k = 0.166% per day expected return on investment, or 61% per year. 55% after commission.
I'm not familiar with other places to invest Bitcoin. What is the usual rate of return? At what point would JD's expected rate of return become unacceptable?
I don't know. In the "real world", +55% would be pretty fantastic. I just guess in the world of bitcoin, it's not that much, especially considering the (substantial) risk to the investment on j-d. But I can only speak for myself, others might think 55% is more than enough.
EDIT: Wait. Why 55%? It's compounded interest, so: 1.00166^365 ~= 83% before comission
