In my opinion, bitcoin is the best investment at this time. The other options are either too risky or scams. Do your own research and be careful before investing.
The ZCash could be the best invesetment in the long term. But the price now is too high to be investable.
Zcash is a totally BS investment. In a month time, mining diff will be so high it won't be profitable to mine it and it actually offers nothing BTC does not already offer. So, just another hyped coin which will disappear in a few months.
definitely,zcash is just waiting for its price to be falling down even far because of the available supply will be added periodically but many and thus the coin will have less value,it's just matter about the time until it happen and will eventually happen
