Lol, okay let's make it clear, if you HODL various well known crypto-currencies with a development team + good community + active support/infromation, it will increase in value. Bitcoin is starting to get too expensive. I recommend putting it in your IRA. But some other recommendations.

#1 (Monero) -  Ring Signatures
#2 (Ethereum) - Vitalik Buterin
#3 Lisk - (New Ether for Javascript)
#4 NEO- (Chinese Ether)
#5 (Mothership) - Not available on many exchanges, this is a hidden gem.
