A suggestion for @HKRJT, just stick with old gambling sites you have invested. If you are looking for new site accept investment, i afraid it would be a scam since we don't know it's legit or not. If you want to know your weekly progress about your investment, you can make your own sheet and then regularly update your investment stats, rather than rely on a site.
If there are already few legit investment gambling sites, why do you need to try new site?
+ 1 here,Why not Stay on those sites that you invested since they are legit and proven for years?finding new might bring you to Losing not unless those advices in first post will be your basis because they are also the best and recommended from the users who had already invested in their gambling platform.
I would recommend bitvest.io because bitvest offers the "locking" funds function, so you can't really withdraw at all before the lock ends which will help if an investor also has gambling addictions like me
so I invest and lock funds on bitvest because it helps me not only to get profit but to also not gamble and lose the funds myself! I haven't tried sites like yolodice and bustabit to form a solid opinion on them yet.
But i'm afraid if Investors comes in full and the funds goes to Huge amount that will trigger the site to Just go and end the site.
I'm not saying that Bitvest or lightlord will do such thing because for long years the site is proven trustworthy but of course other site or the opportunity is always knocking for this.
But after all Just Be warned and advised OP.Goodluck to your another venture.
