I like that you lowered the maximum investment amount up to 3_ETH. This will reduce risks of price manipulation, by whales. And your requirement to the level of the gas is generally a classy move, I might be wrong but I think you are the first who came up with such a strategy. In General, I am more and more amazed at how well and cleverly you do absolutely everything - respect!
It's up to 5 ETH because of the additional 7500 CMT which is almost the value of 2 ETH.
Did you guys received the approval email for the whitelist? I am stuck at phase 2 (reviewing) for like 20 days or more. Is this normal? First it said it will take a few days then 7-10 days and now? What is happening? 
I myself have been confirmed after 11 days. There's maybe some issue with your registration. Have you received an email that you're declined? If not, check the website to confirm if you're decline or not. You could do a follow up on their telegram channel. PM one of the admins to check the status of your application.

Imagine how the work being done behind on a relatively smaller time.
