Yes, there are tons of cryptocoins projects just right now besides of Bitcoin, even some of them almost reaching the level of Bitcoin (Ethereum) and with the ICO-hype trying to be next Kickstart/Sillicon-Valley on cryptocurrencies is basically like chasing digital gold. The question is what coin to mine, not what coin is popular right now... personally i made solid money with dogecoin, was able to buy 2 BTC's when mining that coin was super-cheap.
