XMR is right now in position 22 in coinmarket cap, and it will be kind of hard to see in in the top 10 because its application is more complex than other altcoins.

The complexity of the monero core brings anonymity to the users but at the same time is hard to develop APPs with monero. Isn't like the other coins where you can make easy RPC calls to create sign and push the transactions. The point is, if we have developed something with Bitcoin RPC we can rise that knowledge to build something with LTC or DOGE, but not with monero.

And the anonymous fact is cool, but do people really want to hide their identity? Only the bad guys need that.
