The calm before the storm.

2018 is where all the promises on the roadmap will be fulfilled for altcoins. Now it's only ramping up, because people lost interest after a huge bullrun, so i actually expect this to have low volatility.

Remember, that low volatility can be followed by a huge volatility spike. You can check the VIX index on 2018 01 08 which was very low volatility, afterwards had a huge spike, which was caused by stock prices plummeting up to -10%.

2017 was a big year for Bitcoin, but i believe 2018 will be a big year for Ethereum and altcoins. A lot of attention is on FIAT to altcoin direct conversion, which should decrease the dependence on Bitcoins volume/price.
