The website is nice, though personally I always have doubts about projects that take investments.
Can you explain how this investment system works, and what guarantees does it provide to the said investors?
We share
50% of casino winnings with our house shareholders. (up to 5% daily gross profit in best scenario possible)
There are risks involved with investing including the possible loss of principal. Past performance does not guarantee future results.
You can start an investment from as low as 10 USD through Bitcoin, Litecoin, Dogecoin, Perfect Money (USD) and Payeer (USD). Each user is allowed to have up to 5 active Investments at a time.
can you divest at any time you want? and also, i am finding it hard to use the faucet part because it logs me out after being inactive for 30+ minutes or so, so every time i wait an hour and refresh to go to faucet it makes me log in again, going through captcha and everything again

No, you cannot on bankroll investments because your principal is included in your daily (gross) profit.
However you can stake your funds on Winza through the "HODL program" in order to divest anytime.
We have not faced any session issue so far, sessions last up to 24 hours. What is your current setup? Mobile?
The PIN is the four digits you entered during account registration it is not possible you have skipped that step since it is mandatory.
If this PIN is lost or forgotten, is there any way to recover it ?
Also what is your plan for any campaigns for your site on this platform ?
There is no way to recover the PIN, this is a security measure to make Winza accounts bulletproof. It is your duty to keep your personal account informations in a safe place.
Do not forget to turn on the 2FA in your account settings as well.
