I was one of those first to fill out the VIP Transfer Google form here at Metawin and I can say that it was really easy as long as you genuinely have VIP account to transfer. The reward received was literally free.
First comes, first serves and I believe later applicants might have stricter assessment before the team approve their VIP transfers to the platform.
If the team re-open the program, I expect them to add some new rules and turn the program to a stricter one, not easy like how it originally was when you applied.
Budget and effects from the program will affect their decisions to re-open the program or not. To run the program for a long time, it must bring new VIP members and good income for the business, to make it a sustainable program. It's not easy to become a VIP member so I see the overwhelming application wave probably does not last long and after VIP members from other platforms mostly transferred here, it will reduce pressure on the team budget.
