Can you mention a few crypto casinos that have a great brand name and a few that don't have a great brand name?
I think that almost all big crypto casinos have great brand names. They have great functionality as well. Maybe that's why they became so big.
The obvious answer to your question is that both a good name and good functionality/design are a key factor for the success of every crypto casino and sports betting platform. The problem is that having a "good brand name" is something subjective. Some people could like the name of one website,while others could dislike that name.
Yes I can mention some. Let me just mention two most popular here.
1. Stake.com is a super great name and I'm sure they spend few millions bucks to acquire it. Now, they're the major sponsors of Watford FC in England. The advantage of such premium name in .com is that whenever the name appears on the board or people see Stake on Watford Jersey, they'll simply type Stake.com.
Because majority of users believe every serious site should end in .com. that way, Stake is gaining 100% of it's advertising potential.
2. Sportsbet.io is a bad name choice because it end in the less popular .io which very few users outside the tech community are aware of. Now they're sponsoring, I think, Southampton FC. The downside of such name is that whenever people sees it on advert boards, they usually type Sportsbet.com instead of Sportsbet.io even though there's .io attached to the name everywhere. But people still ignore it and type Sportsbet.com.
As a result, Sportsbet.io is believed to be losing 30-60% of their offline advertising potential.
These two are real examples of Good name and not so good brand name.
