Large institutional money waiting on the side-lines for trading to get established as well as large hedge funds geared specifically to crypto gains, a boost but by far just the beginning of what will be a thoroughly interesting and exciting year for the Crypto-space. Word of mouth around the Christmas dinner table will spread the word to the general population, FOMO will be another driver but new money will arrive and I expect the market cap to be north of $500 Billion before the end of the summer.
Look for Altcoins to recover with greater opportunities to accumulate BTC by swing trading NEO/DASH/OMG/BCC/ETH, all at USD ATH's but very low in terms of Sitoshi's especially in contrast to Aug-17 highs. BTC has sucked the value from the Alts they will be back with a vengeance in 2018 to claim their stake but also their place as tech front runners currently overshadow by the first to market and current king pin BTC .
The whole space will be healthier for a correction of 25% and market confidence will be even greater when it recovers.
Good luck all!
