I assume they cannot do the same as easily as they would like to with 1xbet, because there it is about FIAT, and Russia is sanctioned and it is a centralized system, making it difficult to steal and ghost their gamblers.
It's not really that difficult for them to steal from gamblers through 1xbet either since it operates out of Russia which is why suing them for any issue is not easy. 1xbet if far more popular than 1xbit, but they have their fair share of scam accusations.
Both sites should be avoided at all costs.
