If we want to use the historical increase of Bitcoin ($BTC ) to speculate on the potential future increase of Solana ($SOL ), we can take the following comparison method:

1. **Bitcoin bull market cycle analysis**:

- Bitcoin has typically achieved significant growth during past bull markets. For example, during the 2017 bull market, Bitcoin prices increased 20-fold from approximately $1,000 to nearly $20,000. During the 2020-2021 bull market, Bitcoin rose from $3,800 to over $60,000, a more than 15-fold increase.

- Bitcoin’s halving event usually triggers a strong bull market effect 1-1.5 years later, pushing the entire cryptocurrency market up, which will also have an impact on other crypto assets, such as SOL.

2. **Applying Bitcoin patterns to SOL**:

- If Bitcoin achieves multiple growth similar to 2017 or 2020-2021 in the current bull market, SOL, as a mainstream public chain token with a larger market capitalization, may rise in line with the overall market trend.

- Referring to the performance of the bull market in 2017, if the current price of SOL is around 150 USDT, and assuming it can follow the overall market to achieve 10-15 times growth, then the price of SOL may reach 1500-2250 USDT.

- Referring to the performance of the bull market in 2020-2021, if SOL rises significantly, it may achieve 5-10 times growth, and the target price range may be between 750-1500 USDT.

In this way, we can use Bitcoin’s historical performance as a reference to speculate on the price levels that $SOL may reach in the future. However, it is important to note that market conditions and macroeconomic factors may have an impact on actual price movements, so these speculations are not guaranteed to be accurate.
