I must confess i didn't completely read the links you posted (i have to be in an online meeting in 12 minutes). I quickly scanned them tough, and i've read the other posts in this discussion.

Am i right in my understanding that you're basically exchanging BTC for an altcoin with better security features and call this altcoin pBTC. Then, you transact using pBTC instead of BTC and in the end users can exchange the pBTC back for real BTC and withdraw?

What's the difference between this setup and, for the sake of argument, use coinomi (not a fan of coinomi, but any wallet with an exchange functionality built in will do), fund you wallet with BTC, exchange for XMR, transact with XMR, change it back to BTC and withdraw?
