My speculation on the future trend of $SOL is: In the short term, after the SOL ETF is listed tomorrow, the market may sell the news, so it is likely that SOL will have a short-term pullback; in the medium term, the listing of the SOL ETF will drive a wave of increase in SOL, potentially challenging previous highs. Currently, Ethereum is showing some weakness, and Solana is the most likely to replace it as the 'Dragon 2' public chain. If traditional institutions want to buy altcoin ETFs, SOL ETF will definitely be the first choice. Through this year's waves of rebounds and declines in SOL, I summarize a point for short to medium-term contract trading: in a market where it does not fall below 120 and does not break above 180, do not short below 137 and do not chase long above 158. For spot trading, as long as it is below 120, it can be bought in batches.
