1xbet is currently aggressive on their advertisement and partnership especially on e-sports scene. Which make them trustable because of money they spent heavily on their marketing.
Only now found this message because it was quoted by the poster above.
1xbit also has an aggresive marketing strategy as you can see

And it spends a lot of money to advertise itself, even on this forum.
So weird take from you, as for me. Spending a lot of money doesn't make you trustworthy
