Why not invest in some of the Bitcoin Casinos as an investor; you would earn a monthly or weekly income and help keep your Casinos in net profit. I'm currently an active partner/Investor in a few Bitcoin Casinos my self and the profits get better every month. There's not much work you would have to do as the businesses have their own owners and employees, once you receive a payment from them you can invest back into the business and compound your earnings or invest your returns in another Casino by starting a partnership with another business. This way you'd be growing an investment portfolio of websites from all over the Internet.

The best part right now is that there are more and more Casino based businesses coming online all the time, there's no shortage so the limits the sky the sky is not the limit.
