Zcash coin started trading at almost 20 BTC in late 2016 and crashed below 1 BTC in a week.
Can ZEC/BTC ever go to those highs again? Strictly going by chart yes but practically thinking no way.

Anyway, I got out last time it was near 0.15 BTC or ~$400 USD and have diversified into other
lot cheaper coins with similar technology such as Zencash and Zcoin.
