Hi,
yes, it's opt-in. Here's why: I felt revealing that a person is an investor without this person's knowledge would not be ok. Investments is a "private data", as opposed to all bets, which are public. So if you spot a person with high level, but very little wagered - it's an investor. Especially if this person suddenly jumped to level 16 :-)
That's why it's opt-in. To help privacy a bit.
That makes sense, thanks for the explanation.
Here's how it's calculated:
xp = investment_wagered / leverage
We calculate this for every investment you have (or had). investment_wagered is the amount players wagered using your investment. Suppose your investment makes 50% of the bankroll and players wagered 100 BTC, then your investment_wagered = 50 BTC.
investment_wagered is based on your leveraged investment, correct? So that means that you can't get more EXP by using leverage? Is there a reason for not allowing leveraged investments to gain more EXP, as the investment_wagered would be larger.
Isn't rakeback -EV for you (not talking about investors)? You take 20% commission on profits, which if the expected return = actual return, you would get only 20% of the house edge, but you would be paying 30% of the house edge to players. If a huge whale comes and wagers a lot, wouldn't this/couldn't this be unsustainable?
