^ I confirmed there is, just because I was there before when I was participating in the Wolfbet signature campaign, they had a 7-day streak reward, come back each day and you will receive 0.00000090 BTC.
I just checked it, and it seems the award is 0.01 USDT, not 0.00000090 BTC. I didn't claim it and will try it again later. Maybe USDT is the defaut currency in my account for some reason. Are there any other requirements except just visiting the site once a day to receive those rewards? Can you play with the 0.00000090 BTC instantly, or do you have to wait for 7 days to be credited with the coins?
7-day streak! The first day is $0.01, the second is $0.013... I am not sure about other days so I will not write anything about it! It's a streak, so when you miss a day you start from the first day again! I usually forget to do it, it's too low... it's why I can't remember the prize for other days!
It's the default for all now! We could choose in which crypto to claim a 7-day streak but after the bullish period, they changed it to USDT for all! Even rains are in USDT, 0.01 for 20 users active on chat every 20 minutes! For example, the first day for Doges was 3 Doge coins, the last day was around 15 Doges if I remember correctly! Now you can imagine why they chose to move everything to a stable coin!
When you claim it or get coins from the rain, they are credited at that moment and you can start gambling with them!
