If you want to support the boycott avoid these brands:
Online Casinos:It is necessary to avoid such casinos/bookmakers even without boycott. These are the most famous garbage platforms that have been deceiving their users for years. I'm surprised they haven't been prosecuted yet, but I'm even more surprised that so many YouTube bloggers, especially in the MMA space, are still promoting these scam platforms.
You took the words out of my head, same thing I observed, 1xbet and 1xbit have been scamming people for years, so i support that even without the Russia Ukraine conflict currently going on, they deserve to be boycotted.
And as for being suprised, you shouldn't be, some members here on bitcointalk know that this two casinos are running by known scammers, and yet, they are still promoting them, what is the secret? "Money" money is the secret, the same way they pay members here to promote them is the same way they pay YouTubers to promote them, there's absolutely nothing there to be surprised about.
