Its dual Blockchain liek SAND which has tested the waters for @appics by having the very first steem engine and EOS token, with withdraw and deposit on steem-engine from steem to eos and a listing on Newdex for https://SteemSanDiego.com users to sell their SAND for EOS here https://newdex.io/trade/sandiegocoin-sand-eos

Im very happy to help direct @ackza and @sandiegocoin with @appics maybe @soldier can help get in touch!
