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..
Nice observations you have there. These are all true and I share the demand or the hope that all these very significant issues be resolved as soon as possible, hopefully withing the year 2018. The trust of the people are not without bases. They are trusting and investing into cryptocurrencies and Bitcoin because of the advantages they are giving them. But once the disadvantages will prove to be much heavier and giving them more hassles, these same individuals will pull out their support from crypto. And that is not good to all of us.
