Zcash is a good choice for long-term investments, because there are only 21 million Zcash available and at the moment the price of Zcash is only 61$, so I think that the price of Zcash is very low at the moment and the price of Zcash should be at least 100$ and I think that in 2021, Zcash will be able to reach this mark, especially after all the updates from the Zcash team which was in this year.
