Aster was the biggest buzz this year. At the time, I happened to be researching market-making strategies and saw that Aster had airdrop expectations, so I used it to practice. The early strategy wasn’t optimized, which caused some losses, but after optimization, it was able to generate stable profits. I even held a strategy sharing session back then. In the end, 500U resulted in a 40U loss, but I earned 70U in rebates for myself, so the net cost was -30U. If the airdrop were held until now, one account could sell for 1.5wu. There are still plenty of opportunities in the crypto space.
