It is a scam, OP. Those are always a scam.
Any services which offers to you some kind of advantage over other gamblers, asks you for money or some kind of subscription and takes places on Telegram, are 100% a scam.

Besides, of that 1xbet and 1xbit are also quite shady services which are supposed to be avoided at all cost, so please, if you are being sincere about this question of yours in "service", then take our word and stay away.
