Hurriedly made up name is the worst gift you can give to your start-up. If you just want to be on crypto community to grab few coins, no problem. But if you really wants to go big mainstream, you need to rethink your name asap.
You can have the best name in the industry but if you have a bad platform and a bad policy it will not bring you anything or you can have casino123 as a name and be the biggest name in the industry, here in the casino industry it's not the name that carries a casino is its reputation and features that spell the difference.
Your argument is valid but I think over 90% of business owners and startup founders are going to strongly disagree with you. A poor domain name is capable of cutting your market share into half or more, while a great domain name could significantly increase your market share. That's one of the reason businesses are investing millions of USD in quality domains. Your name must inspire confidence to most users. Else, your good platform will amount to little or nothing.
One of the most important value asset your business could have is a premium name that is easy to remember, easy to type, appealing, short, brandable, and easy to pronounce. These characteristics leads to improved brand equity.
