I'm been using Steem engine a lot recently (mostly selling Steem Monster "Dark Energy Crystals", and trying to buy low and sell high with Bitcoin Pegged), and I noticed that there's now a "SNAX pegged" on there.
... One problem... Steem Engine doesn't yet have a means to deposit Snax into the exchange, which is a shame. As much as Snax offers a means to get rewarded for social activities on whatever platforms it gets tied to, the main potential it has to become valuable is exchange for other cryptocurrencies. For now anyways.
I don't know how they're currently doing it, or how they plan to do it soon; but hopefully there's a solution to this soon.
