A shark sold $13.4 million of bitcoin, ether and JCT in minutes. The buyer made 81,836 trades in a month

What DeepSea's data shows

DeepSea's live trade feed logged two large shark trades on BNB Chain at 12:30 a.m. ET and 12:32 a.m. ET on November 8. In the first, a wallet ending in 0f10 sold 2,407 ETH (Binance-Peg ether) for $5,376,645. In the second it sold 298,605,399 JCT for $805,637. Each time, the buying side in the same transaction was a wallet ending in 8771.

The seller's wallet page (DeepSea name Hold0f10, labeled shark) also shows a sale of 95 BTCB (Binance-Peg bitcoin) for $7.20 million a few minutes earlier. The three sales add up to about $13.4 million. Its total assets now read $28.70 million, all of it USDT0, a version of the Tether dollar token.

Its record on DeepSea is poor: minus $1.67 million over 7 days and minus $1.75 million over 30 days, a 0% win rate, 145 trades and $280.94 million of volume in 30 days. DeepSea's realized PnL table (12:30 a.m. ET) counts just five closed trades in 30 days, none of them winners.

Data: DeepSea (desea.io), checked November 8, 2026, 12:35 to 12:55 a.m. ET.

Who was on the other side

The buyer, ending in 8771, is a very different wallet. Its DeepSea page lists 81,836 trades and $1.14 billion of volume in 30 days, a 42% win rate and +$1.48 million over 7 days. DeepSea's PnL table puts it at +$1.52 million on 3,072 closed trades in 7 days, and shows the same address trading on Optimism, Arbitrum, Avalanche and Polygon. In the four minutes after the ETH trade it also bought small amounts of UAI, LAB, MYX and other BNB Chain tokens.

A wallet that trades thousands of times a day with a win rate under 50% looks more like an automated trading or market-making operation than a single investor. DeepSea does not say who runs either wallet, or whether the two are linked.

Checking the prices

CoinGecko showed ETH at $2,232.59 at 12:43 a.m. ET, which values 2,407 ETH at about $5.37 million, in line with DeepSea's $5.38 million. BTCB traded at $75,657 at 12:50 a.m. ET, so 95 BTCB is about $7.19 million.

JCT, the token of the computing marketplace Janction, was at $0.00276, down 11.1% in 24 hours and 49.2% in seven days, with a market value of $31.8 million. The 298.6 million JCT sold are about 2.6% of the 11.49 billion coins CoinGecko counts in circulation. Two days earlier, the same wallet's page shows it buying JCT in lots such as 77.31 million coins for $249,400, about $0.0032 each.

Why it matters

Selling into a dollar token takes a wallet out of market risk. DeepSea logs the other side of the ETH and JCT trades as wallet 8771, not an exchange. The seller's page also shows it has done this before: it sold 95 BTCB for $7.23 million four days ago and 300 million JCT for $875,400 two days ago, then bought both again. We could not open BscScan, the BNB Chain explorer, in this run to trace the route, so the matching of buyer and seller rests on DeepSea's trade log.
