According to The Wall Street Journal, several early Bitcoin supporters, including Gemini co-founders Winklevoss brothers, are heavily betting on privacy coin Zcash, believing its shielded transaction mechanism aligns more closely with Bitcoin's early ideals. Grayscale filed Form S-3 on May 8th, intending to convert its Zcash trust into the first privacy coin spot ETF. ZEC is priced at approximately $597, with an annual increase of over 1,400%.
