Instead of gambling against the house why not bet on the house? The house always has the advantage so it would be the logical thing to do. Let me explain how you can do this
The odds are always in the houses favor and in the end will always win and be profitable. What if I told you there was a way you can invest in an basically be the house and take a fair portion of the profits. There are online Crypto-currency casinos that encourage you to do so. Reason being they do not have enough money themselves to have the big bankroll needed to run a casino, so they ask you to invest and because it is your money you will get a percentage of the profits. At Crypto-games.net they share 70% of the profits.
Here is an excerpt from their site "You can invest in the house bankroll and earn a portion of the site's profit. We share 70% of the profit with investors, the rest of the profit is invested in marketing, development and maintenance. Profit is calculated once every hour. The minimum investment period is 24 hours."
Crypto-games.net is a long running and trusted website/casino. They are very transparent, you can log in and look at the profit/loss charts for each coin as well as the bankroll for each coin, which makes it easy to decide which is best to invest in now. They allow you to invest in Bitcoin, Dash, Dogecoin, Ethereum, Gridcoin, Litecoin, Peercoin, and Monero. A lot more choices than any casino I've ever seen. There are other sites that allow you to invest in the bankroll such as SatoshiDice, however they only share half of the profits.
Happy Investing!!
