According to Gordon (@AltcoinGordon), major cryptocurrencies like Ethereum (ETH) are projected to reach $10,000 and Solana (SOL) could hit $1,000, with altcoins potentially experiencing stratospheric gains. However, Gordon emphasizes that without a clear profit-taking strategy, 99% of traders risk missing real profits due to common mistakes such as selling too early, rebuying at the top, or holding too long and round-tripping their gains (source: Twitter/@AltcoinGordon, June 4, 2025). This highlights the critical need for disciplined exit strategies in crypto trading to maximize gains during market surges.
