Thanks for your replies.

I was referring to this link https://mintdice.com/guide/investing from free guides (investing). Which I cannot click the "Casino Bitcoin Investment".

I haven't tried investing into any casino bankrolls but I do have some ideas since some relatives and friends did it some years ago. Betking bankroll investment then did very well like around 4% rate of returns monthly.

I read that there is an estimated 10,000 bitcoins gambled yearly (around 27.4 btc daily) on Mintdice. With 1% house edge then there will be around 100 btc in a year or 8.33 btc monthly earnings. I am curious on the size of the current bankroll.
