Some says that there is a bubble in btc , but truth is btc mostly used on the Internet and even used for escape from taxing in China, India or even in America. I think with this situation goverments should change their policy about blockchain. Anyway until that time if you stored some btc before, you can enjoy now and celebrate new year with btc . And if you don't just try some altcoins like DASH or Monero.
Have a good year
