Moneypot has quite a decent of wagered volume there, before and after the transition to the new owner so there is no way that you have not got any increase or decrease to your investment. The only possible reason is that you are only putting a small amount like 0.01 % so you didnt notice much increase in your investment
Dunno...But, they just took a big hit today which is one of the risks. Investors lost around 30% of their investment. It happens....some whale came in and started betting all maniac on the plinko site and had a huge payday a few hours ago. So, house doesn't ALWAYS win. In the the long run they'll win but it's really not a short term investment opportunity. You have to go long if you want to invest and make real profit on a gambling site.
