There are still many problems in crypto:
- This year we had many HARD FORKS.
- high transaction costs ($40,- btc)
- transaction speed
- realy decentralized? Who are the big players, who decides the hard forks..
- almost all crypto needs to be payed with btc
- ICOs - to much greedy and some good projects
We arent there yet. But these problems wil be solved

Maybe in 2018..
Lightning network will resolve the slow confirmation speed,and good ICOs are coming in with artificial intelligence projects this year we hope that alts will do good than lat year.
