The mad dog wave, if there was previously a conflicting sentiment between the crypto circle and Wall Street, then after breaking through 4000, there should actually be a united force. Those who needed to sell have sold, those who haven't sold will be reluctant to part with their assets, and those who haven't bought will feel uneasy. So, people are starting to buy into the Ethereum ecosystem. After all, Wall Street hasn't finished buying yet, and their costs are incredibly high. The road ahead still holds a lot of expectations.
