Chainlink (LINK) is often remembered as one of the early giants of the blockchain space, delivering powerful oracle solutions that connected smart contracts to real-world data. Investors who secured LINK early reaped massive rewards. But for those who missed that train, a new presale is shaping up to be the next big opportunity. BlockchainFX (BFX), now priced at just $0.024 in presale, is being hailed by experts as the best crypto to buy before Q4 ends.
