According to crypto analyst Ali Martinez, SOL price might go up to $90 making it become a viable alternative for ETH. He points out that SOL should keep support above $68.20 else risk falling to $47. SOL has highly appreciated compared to the beginning of this year. Martinez cautions LINK investors about the token’s price action beyond a critical support area. He also mentions crucial support points for BTC at $43,700, along with further growth to approximately $47,300 assuming the upward trend remains in full force and emphasizes these crucial support and resistance zones grounded on wallet activity.
