Privacy is one of the most glaring characteristics significantly lacking (or altogether missing) from how Bitcoin is most often used today. As a result, the market sector of privacy currencies has rapidly grown. In their investment thesis for Zcash ($ZEC), Blocktown Capital explains,
"Any amount of privacy previously associated with bitcoin has been all but eradicated by tightening identity requirements for cryptocurrency exchanges and bitcoin’s permanent ledger of on-chain transaction history. [...] It is critical that bitcoin does not facilitate any further erosion of financial privacy from the state. "
Dozens of blockchain protocols are actively developed to meet the need of robust transactional privacy, and Blocktown is placing their bet on Zcash, arguing that "Zcash may be the much needed deterrent to government overreach" by virtue of its privacy features. Read their complete thesis here.
"If state authorities ever push too hard against financial privacy though, the most private cryptocurrency in existence is here — Zcash."
