Let's clear this one up. Back in November, Uphold themselves stated that Voxels would be the only other crypto besides Bitcoin used on the site. When I stated it here at the end of last year, it was true . It was originally stated by Anthony the CEO of uphold in a letter they sent out to all their investors. 5 months later Uphold decided to add ETH and LTC. I'm not sure why that's a problem because it allows you to trade LTC and ETH for VOX.
