83,700,000 tokens exchanged for 663 ETH! A remark from a major figure in the mining community, "I'm a bit regretful," sparks heated discussion. F2Pool co-founder Wang Chun revealed that over the past year, he received approximately 8,370,000 SPK rewards from Spark, which he sold entirely on CoW Swap, converting into about 663 ETH and 1.4 million USD. But he then candidly said, "I'm a bit regretful now." The reason this statement drew attention is because it reflects a very real logic in the crypto market — the choice between short-term gains and long-term value. Often, the asset's story ends at the moment of sale, but its value story has just begun. In the crypto world, volatility comes not only from price but also from differences in perception. What you see is profit; what others see might be the future.
