I think something like #CryptoUser is already quite popular, why not just use that? Are you trying to build another hashtag to market your business or what?
I agree with DarkDays, rather than creating new hashtag for the same purpose we should try to post more on existing and popular hashtags.
There are not many people who use crypto in their daily life because most of them are investors not consumers. Lending and cross border payment are some of the successful financial space for crypto and i think we need to focus on that rather than daily use.
