You made a classic mistake traders always make with trending coins. Buying due to FOMO, and now you are at a point where you have to hold the coin until it goes back up at least to the price where you bought it or even more. Problem is, you may have to wait for years for this to happen, especially if crypto winter is to start soon
Crypto newcomers are incentive to the idea that from cryptocurrencies they will gain huge profits with small investments . At the point they think as much as they add value they will get a retun.
I guess that's what you thought and it didn't happen

If you were lucky enough, doesn't mean this will be a general rule applicable for everybody. Zcash is one of the few successful project in the crypto space since its early days, but this doesn't mean its price is profitable everytime to invest in. Those who bought it before 2017 and held it since then are surely wealthy ones by now. While others who bought it few years ago might got small profits from small flactuation but not a big amount considering none of them bought worth of million dollars in Zcash.
I suggest you to diversify your investment wallet because it's always risky to put all the eggs in one basket. Or to stick with bitcoin only because is the most trusted project that would never fall or price decline for a longtime.
