Many people within the cryptocurrency environment are on a quest for fungible digital currency transactions. Some have opted to use altcoins while others patiently wait for Bitcoin implementations like Schnorr signatures and Tumblebit. For the time being, there is a platform that Bitcoiners can experiment with that uses coinjoin transactions called Joinmarket. https://news.bitcoin.com/joinmarket-community-bitcoin-fungibility/
I love coinjoin! An easy and cheap way to mix up your coins a little bit :)
