It means that you are also saying that Barcelona, one of the biggest football clubs in the world is also scammer because Barcelona is also having partnership with 1xbet which is known as the main site or sister site of 1xbit?
For your information
1xbet.com is different from
1xbit.com don't put the two in the same sentence, 1xbet.com is a legit bookmakers and they are not crypto gambling site they uses local fiat, I'm a big fan and I've been using them for a long time now. What you see on the Bacelona official page is 1xbet.com not 1xbit.com. 1xbit.com is a clone site of 1Xbet.com
I'm mycelium user and I noticed about the ads since few weeks ago. To be frank I'm disappointed to see the ads of 1xbit in mycelium, but I do not think that Mycelium is scammer just because of the ads.
If you rent out your apartment to kidnappers what are you? They are not scammers but they are dining with scammers. Precautions is better than cure.
