At Bumba, there is the possibility to invest in the websites Bankroll. This means you own a percentage of the website. Minimum investment is of 0.01 BTC. The house takes 30% of the winnings, to pay for hosting, add new updates, promotions, etc
As an example, we’ll say there is a bankroll of 1000 Satoshi’s invested by 2 investors – Investor A and Investor B
- Investor A put in 900 Satoshi’s (90% of the bankroll owned).
- Investor B put in 100 Satoshi’s (10% of the bankroll owned).
- Player X decides to bet 10 Satoshi’s (1% of the total bankroll) and loses.
The House takes 30% from the profits, leaving a total of 7 Satoshi’s to be shared amongst the investors.
As such, Investor A receives 6.3 Satoshi’s and Investor B receives 0.7 Satoshi’s.
Now Investor A’s new balance is 906.3 Satoshi’s and Investor B’s new balance is 100.7 Satoshi’s
In order to protect the sudden drop of bankroll, we have put a protection on the investments. If you decide to cancel the investment within 3 weeks (21 days), we will take 1.5% from the investment (including profits).
Bumba wishes to advice any potential investors to only put in what you can afford to lose. Investments can make you money, but on the flipside, can also lose you money.
