On December 30th, on-chain data revealed an interesting trading story. According to real-time tracking by a monitoring tool, an experienced short seller active on a leading perpetual contract platform made a large position adjustment within the past 3 hours.

This trader's actions were quite decisive: first, they cut 43.3% of their ZEC short position, closing approximately $713,000 worth of positions. Then, almost without pause, they immediately shifted funds to LIT, opening 44,100 short positions at $2.82 per coin, directly pouring in $125,000 into a new position, and they are still adding to the position as of the time of writing.

This address is not unknown. On a top perpetual contract platform, it is currently the largest short holder of UNI and ASTER, holding 22 active short positions. In early November, they closed nearly half of their short positions, but in recent days, they have started to aggressively add to their positions again, with the total holdings reaching $25.72 million.

What is most noteworthy is this trader's focused strategy: they specifically target short-term fluctuations of altcoins. This month, they have successfully closed 10 short units, accurately capturing opportunities across various altcoins. Their performance is quite impressive — with an 80% win rate over the past 30 days, and a total profit of $82.27 million so far in 2024. Such a record certainly draws market participants' attention, especially for traders trying to understand how professional short sellers seize opportunities in altcoins.
