I can confirm this! Also $250 for completing KYC Level 2 is crazy.
I did get an e-mail this summer I think it was in August like "Complete Level 2 KYC sooner than 14 days and get $25 free"
So I completed KYC 2 at Stake this summer and I got the $25 which I was happy with.
There is 1 lesson to be learned from that, never take the first offer.
When my friend began to get these emails they also started with 25$. Some time later is was 50$.
Then the announcement of the upcoming mandatory KYC came and they offered 50$ again. Some weeks later it was 100$ and then up to 250$. Told him from the beginning to wait, he wanted to do it when they offered 50$ but I advised him to wait again because I had a feeling it might get more, and so it did.
