Whatsapp Binance/crypto spam

I've been getting spam messages in Whatsapp since this week.

I'm getting added to "Binance" teams or a "Bitcoin company" asks me to hitch a gaggle. In fact an instantaneous report and block, but nonetheless annoying.

And it is a bit strange as my phonenumber has by no means been targetted by spammers before apart from an SMS a few month in the past. I don't use this quantity for another crypto change (or crypto related thing) so now I'm wondering if there was a leak of private knowledge (at the very least cellphonenumbers) from Binance?

I imply I do know I get targetted on Telegram because I be a part of crypto associated teams. Or right here on Reddit because I publish right here (don't message me, you're losing your time). However my personal cellphonenumber? No one has that... In addition to Binance... And now some spammers... What occurred?
