Just look at Monero github, they have a very strong development team and strong community. It's also the only currency with good privacy - the other competitors are DASH which is actually less safe than just using coinjoin with bitcoin, and Zcash which is not trustless (you must trust the founders really deleted the data used for starting the geneis block otherwise they can see all your transactions).

If there's anything that has the right foundation to really join bitcoin and ethereum up the top its Monero.
