Early Bitcoin billionaires clash again: Winklevoss brothers compete with DCG for dominance of Zcash ecosystem According to Bloomberg, the privacy coin Zcash (ZEC) has risen by approximately 3000% over the year. Early Bitcoin billionaires and Gemini co founders, the Winklevoss brothers, and DCG founder Barry Silbert are intensifying their efforts to compete for Zcash's mining and investment products. In terms of ETFs, DCG's Grayscale launched the first Zcash ETF in the United States in August, and the Winklevoss brothers also submitted their own Zcash ETF application this month. In terms of mining, both mining companies Cypherpunk Technologies and Fortitude Mining, which are supported by both sides, plan to invest tens of millions of dollars to expand their computing power. The former currently accounts for about 20% of the network's computing power, while the latter claims that the deployment of new computing power will also reach 20%.
