Most of those are indeed scams, very rare code forks are transparent and introducing real changes that will impact users. Not the case of Verge that mostly use marketing and cosmetic changes, once in a while copy code of other currencies to bump version and try to pump their value. Their clients could be used on most of other bitcoin forks with a few changes and would have the same performance on similar performance, what doesn’t make Verge any special. But you can qualify anyone as you please.
