Sushi(dot)com would be very professional and also retain resale value that would appreciate over time. The value will undoubtably increase over time and you only have a price without even negotiating.
While I agree that sushi.finance is a good start, eventually traffic will start leaking to sushifinance(dot)com, also sushiswap(dot)com? There is no such doubt with sushi.com and the amount of PR from the purchase would also create an interesting effect that could be harnessed and used as positive.
One major point I’d like to highlight is the fractionation of so many different domains in use and that this doesn’t look professional and is confusing to new and even more experienced users. The flow should be seamless and all domains and associated products should be consolidated onto one domain with all associated names 301 redirected to keep Google in check and traffic moving as usual. Really need to get all the associated brands and extensions, including .com all consolidated and redirecting neatly to catch all traffic, likely the horse has bolted here somewhat.
Anyway, these are my pet peeves, the simple things that are complex in their simplicity and send huge messages about brand and intention. If (when) SushiSwap gets to $10, I’d strongly consider taking a professional approach to something many overlook. Nobody will ever forget sushi(dot)com and the daily traffic will convert more users and make inroads over time with the gain of ranking for sushi in Google!
Also is the branding ‘Sushi Finance’ or ‘Sushi Swap’?
The devil is in the details.
