Several coins are down yes, and some still have some great value in them. I think once the Bitcoin upgrades are in place, the new BCC will continue to grow as Bitcoin did, provided it doesn't have any mishaps early on to prevent it from doing so. I also believe many of the alt coins will recover once investors see everything has went smoothly. I think 2018 will be a fine year for Crypto as more and more are joining the community. Nvidea is also working on its new hardware designed specifically for Miners. To the Moon Baby!
