Sign

Sign is a bare, minimal cryptocurrency name, and that sparseness is both its point and its weakness. By our assessment, it sounds like something meant to imply proof, marking, or digital approval, which gives it a little more seriousness than a joke token. The trade-off is obvious: a word this plain is easy to remember but very hard to make distinctive, especially in crypto where names compete for attention. In practice, that means the project would have to do the heavy lifting itself, because the name carries almost no story. It sits on the sober side of the category, but only just.
