Edit: I asked him and he got the same email as you, but with the 250$ bonus if he does it in the next couple of days. 
Surprising step by Stake. Looks like they have decided to make the KYC verification mandatory for all the users. I have to complete the level 2 KYC verification before the 1st January of 2025 to continue my betting activity at Stake.
And they have indeed offered me $250 if I complete this before 7th October. I think the bonus amount is same for all the users. Or it could based on users VIP rank.
