clever indeed, but the concurrence is HUGE, and tecnology is not that simple to change. Can they migrate to Graphene as BitShares or to DAG-tec as Byteball... I think no
Both of them have an obfuscation and good governance. PeerPays have great staking... as of promotion who is better than Steem? (it's graphene-based too, and so is tecnologicaly more advanced)

There are way more factors to put in account. Believe or not I researched about 300 projects and this is my choice. And of course you are free to make your favorite list :)

I will eventualy. But anyway, don't get me wrong - PivX is great, I considered it thoroughly, but there some real competition there. So we will see.

Thanks again for your post an answers!
