Zcash ($ZEC) hit a two-month low of $962.85 on Wednesday, one day after Grayscale pledged $1 million to nonprofits and projects that support the Zcash network.

As of 12:20 pm UTC on Wednesday, Zcash’s 13.5% decline led 24-hour losses among the 100 largest cryptocurrencies by market capitalization. It was down 24.5% over seven days. The drop came amid a broader crypto sell-off that saw Bitcoin (BTC) fall 5.8% and Ether (ETH) 11.6% over the same period, according to CoinGecko.

Crypto prices fell further on Tuesday after US consumer prices rose 0.4% in October from the previous month, exceeding economists’ forecast of 0.3%.

Zcash allows users to make shielded payments, keeping sender and recipient addresses and transaction amounts out of public view.

Zcash was a major driver of this year’s privacy-coin rally, rising 138% in the 30 days leading up to Sept. 7. It remains the largest privacy coin by market value, representing about 60% of the $28 billion category tracked by CoinGecko. The category’s total market value declined about 7% over 24 hours.

$ZEC was trading above $1,370 as recently as Friday, when Zcash activated its NU7 upgrade. The upgrade reduced the target interval between blocks from 75 seconds to 25, with the aim of speeding up transaction confirmations. It also rendered about 12,224 $ZEC held in the network’s original privacy pool unspendable.

Grayscale converted its Zcash Trust into a US spot exchange-traded fund (ETF), which began trading on NYSE Arca on Aug. 25. The fund saw about $15 million in net outflows in November through Monday, after about $46 million in October, according to SoSoValue.
