One suggestion, which may be an opportunity for bisq:
-Iota is a currency without mining and without blockchain
-Each transaction forms a vertex of a graph and has to secure the two previous ones, constructing two arcs towards them. The network is constructed so that it never goes through those vertices
-Iota is quantum secure: can not be break with quantum computers
-The network becomes stronger as more transactions are made
-Iota is 100% premined
-No fees for transactions
-You can see the live network here: https://tangle.blox.pm/36
-The wallet can be downloaded here: https://github.com/iotaledger/wallet/releases11
