$300 to earn $104,850? Analysis of 5 Potential Coins How does Pectra ignite ecological coins? L2 explosion: Blob capacity doubles down and reduces L2 fees, and transaction volumes such as Arbitrum and Optimism may skyrocket. DeFi upgrade: simplify smart accounts, optimize user experience of Uniswap and Aave, and expect expected capital inflows. Pledge boom: EIP-7251 is beneficial to pledge agreements such as Lido, and institutional funds will push up demand. Recommended 5 Potential Coins: Arbitrum (ARB): L2 leader, TVL leads. Pectra's fee reduction may push ARB by 2–5 times (3–6 months). Optimism (OP): The developer ecosystem is strong, and the L2 boom may rise by 2–4 times (3–6 months). zkSync (ZK): Zero-knowledge proves the star, supported by EIP-2537, with 3–6 times potential (6–12 months). Uniswap (UNI): DeFi king, smart accounts are good for DEX, expected to be 1.5–3 times (3–6 months). Lido (LDO): Leading pledge, EIP-7251 attracts institutions, with an increase of 2–5 times (6–12 months). The truth of the profit: $104,850 (34,950 times)? Pure exaggeration! It is difficult to even achieve meme coins within 1 month. Realistic expectations: $300 to diversify the above 5 coins, and you may make 2-5 times ($600-$1,500) in 3-6 months, and you need to seize the L2/DeFi boom. Risk warning: Altcoins fluctuate greatly, with 50–80% retracement common. New Pectra features may have vulnerabilities, affecting the security of the DeFi protocol. The deadlock in Sino-US negotiations may suppress market sentiment. Investment advice: Spread layout: $300 is divided into 5 coins ($60 per coin), reducing risks. Hold your position patiently: Target 3-12 months, do not pursue the dream of getting rich in one month. Risk control is king: set a stop loss of 20–30% and take profit of 2–3 times.
