House bankWhen I first bought crypto I decided to be a proactive investor in the ecosystem. Looking for crypto-on-crypto returns I invested in altcoins, crypto startups, and the Just Dice house bankThe altcoins and startups failed as investments but the Just Dice house bank was stellar; returning more than 32% per year plus entertainment value! House bank investment is now available on many crypto gambling sites but as we found out on our real-life dice investment comparison results are mixed at best.

How does investing in the house bank work?

When gamblers bet against the house it must have a pool of funds available to pay from when the gambler wins. This pool of funds is known as the house bank. The bigger the house bank is the higher the bet limits can be as a bigger house bank can afford to make bigger payouts.

Normally the house bank comes from the site operator themselves, but in the crypto gambling investment model anyone can invest in the house bank. When a gambler wins, his payout comes from the house bank and all investors lose money. When a gambler loses, his money goes into the house bank and all investors make money.

Given there is a mathematical advantage to the house, the house bank and all investments in it should increase over time.

How much of the gamblers’ losses you get depends on what % of the house bank you have provided. If you have provided 0.3% of the house bank you will get 0.3% of the profits or losses. Well nearly; the operator takes a % of the house profit, typically 10%. This is called a 10% commission on investors’ profits. So if you invest 0.3% of the house bank you will make 0.27% of the house profit with 0.03% going to the operator.

How much can you make?

To work out how much you can expect to make on a crypto gambling investment platform you need to multiply the investor’s edge by the number of times the house bank is turned over per year then apply to compound. That will give you the expected annual return.

expected annual return = investors edge x turnovers per year

investors edge = house edge – commision

turnovers per year = 365 / turnover length in days

For example, a 1% house edge with a 0.1% commission to the site gives us a 0.9% investor’s edge. If the bank takes 30 days to turn over that is 12 turnovers per year. That would give us an expected annual return before compounding of 10.8%

investors edge 1% – 0.1% = 0.9% turnovers per year 365 / 30 = 12 expected return before compounding 0.9% x 12 = 10.8%

Then use a compound interest calculator by plugging in the expected edge before compounding (10.8% in this example) as the “annual interest rate” and set the number of turnovers per year (12 in this example) as the # in “interest to compounded # times per year“. That will give you the expected annual return after compounding which in this case makes 11.13%.

House bank turnover is how long it takes an amount equal to the house back to be bet. To get this figure you have to check the site’s stats and work it out manually. We calculated this and other key stats for all major operators on our dice investment comparison.

What are the risks?

Gambling risk

In the short term, the gamblers betting against the house bank could win, causing investor losses. In the long term, investors’ mathematical advantage mitigates this risk. So does the fact that the operators limit the maximum bet to 1% or less of the house bank. This means if a gambler hits 5 max bets in a row the bank has only lost 5%.

Counterparty risk

The site’s operators could run off with your investment, have it stolen by hackers, lose all their records in a technical glitch or underreport profit. We detail the possible scams and how to prevent them. Carefully choosing where to invest and heeding our crypto dice reviews mitigates this risk.

Legal risk

The site could have your funds seized by anti-competitive law enforcement. You can leave an emergency withdrawal address with the sites to mitigate this risk.

All risks are reduced by diversifying your investments across multiple sites. See each site’s investment product detailed on their website for full details.

Alternative investment models

There was one other crypto gambling investment option before Initial Coin Offerings (ICOs); buying shares in Bitcoin Rush at Havelock Investments. Havelock Investments is a bitcoin-denominated stock exchange run out of Panama. It’s a good platform that allows anyone to invest in crypto-related companies with no barriers to entry such as minimum investment amounts or ID requirements.

One such listing was Bitcoin Rush which paid dividends and produced investor reports. We didn’t recommend this option because we think Bitcoin Rush has an uncompetitive product and questionable integrity. Investors lost most of their investments when Bitcoin Rush changed to an ICO model.

We still think this investment is an interesting option, the main problem is that you trust Havelock as a centralized 3rd party and this model has been superseded by ICOs.

I have worked with several companies in the past including Economy Watch, and Milkroad. Writing for BitEdge is highly satisfying as I get an opportunity to share my knowledge with a broad community of gamblers.
