I'm completely sure about the validity but there is some cause for suspicion here.
Mainly, concerning the two sites that are mentioned
Code:
https://tbs22http.dark-a.com/ and https://netent-static.casinomodulle.com/
Secriously, this site is becoming a disaster in the bitcoin community, its father site 1xbet has bad reputation in fiat gambling industry, but this time they are nortorious in bitcoin industry. Shame on them.
