Alphractal CEO Joao Wedson has advised investors to avoid purchasing XRP, BNB, and Solana, citing unfavorable risk/reward ratios after significant price increases. XRP has surged 492% since November 2024, while BNB and Solana have gained 79% and 33%, respectively. Wedson suggests considering Shiba Inu, Dogecoin, Cardano, and Toncoin, which he believes are in more favorable accumulation phases.
