Very "smart" to send this bonus drop with way to high requirements and a 1 hour window to claim at around 4am GMT, makes total sense.
95% of all European customers will miss this one.
Don't forget this is a special bonus for loyal players meaning they bet at least in the last 30 days that's why it's only posted on Telegram
Meanwhile, the main bonus is being prepared it is possible that all users can claim it and usually unconditionally
1 hour is normal time if it has not been claimed until it reaches $50K then the code will be valid for an indefinite time.
So wagering 15k like me for example is not loyal? I just make sports bets and its not as easy as betting on 1.01 in the casino.
Also I specifically wrote this because of the time of the bonus drop, its night/super early morning in Europe, almost nobody of the European players will get this drop because they are sleeping.
