$SOL The currency $SOL is one of the most prominent digital currencies that has gained significant popularity recently, thanks to the fast and efficient Solana network. I see that $SOL has a promising future, especially with its increasing use in DeFi and NFT projects. Alongside SOL, I also monitor the performance of $ETH as it is the backbone of many decentralized applications, and also $BTC as it is the first and most stable digital asset in the market. These three currencies currently form the core of my portfolio, and I see that they combine security and potential growth.
