I was surprised too I have no idea why Rollbit is surging atm
Tons of reasons obviously and each time they made a new update on the site, I usually posted it on this thread. The latest update would be the hourly buy and burn feature from ROllbit as well as 0% fee on the RLB lottery. So that literally makes RLB valuable as you can use them to join the lottery although you probably wont win unless you have decent amount

I mean anything related to casinos doesn't have to be about RLB, since creating an account in 2021 I've only seen 3 emails from Rollbit including the confirmation email. I'm also not very active on Twitter only use it when participating in an event

You also never received a promotional email right?
Im not really sure about this as I use a spam mail to register on most sites around but I do notice that compared to some other sites out there, Rollbit sent far less promotional email for sure
