There are plenty of opportunities in Crypto. Don't get distracted by all the new coins with fancy use-cases and ICO this and Whitepaper that. If you are relatively new to Crypto I would suggest looking at some of the older coins and see how they have done over the years.
Feathercoin - Fast transactions, the algorithm has changed from Scrypt to Neoscrypt to make it GPU-friendly.
Unobtanium - Very rare, merge mined with BTC.
Peercoin - Pretty sure this coin was the first staking coin.
Terracoin - Another staking coin, now with masternodes.
Each one of these coins is still around and active. Don't be caught up in the hype of new coins without looking at some of the old coins.
It's getting tough for mineable coins to get along with the new generation coins with faster and cheaper transactions. Bitcoin is leading but many of it's old competitors are lagging behind. I don't see any reasons for old coins like litecoin, dogecoin, peer, prime or feather or the ones you mentioned have a better rise than bitcoin.
