Not so much suitable names I can suggest. What do you think about *coinasotra" , "trade here" , "cointra"...
The choice is almost difficult, a group of people can find good results in brainstorming. Doing exercises in brand is also a good option.
What are you aiming to do?
I am aiming to launch my own Cryptocurrency Exchange Software which has all the latest feature and must be white labelled. And above is it Coinasotra or coinsutra?
I think it is coinsotra as coinsutra is being used by other site already although coinsutra is not an exchange. Looking for a name for your project is not something easy thing to decide. I can only suggest that you choose short name only which is common used word in this industry, easy to remember, easy to type, so people will be more aware about your site.
Oh my goodness, is exchange the only business that we have in this cryptocurrency, everyone is busy here and there creating cryptocurrency exchange that we already have lots of them in the market and yet to even be patronized.
The other exchanges closing down, do you think that they don’t have full features too that can compete with the ones at the top, they have, but no matter the feature they have, volume is the problem, we need more projects that will create adoption of cryptocurrency than exchange, if you develop you own exchange now, which project do you want to get listed in it, now that we have few upcoming ones.
