SOL$

- You can buy and sell $SOL$/USD on exchanges like Binance, Coinbase, Kraken, and others.

- The profit rate depends on the difference between the purchase price and the selling price.

- Example:

- If you bought 1 $SOL at a price of 150 dollars and sold it later at a price of 180 dollars, your profit is:

\[

\text{Profit} = (180 - 150) = 30 \text{ dollars}

\]

- Return rate (%) = \((\frac{30}{150}) \times 100 = 20\%\).
