What time is best to buy ETH?

I'm wondering, what time of day would be considered most advantageous for purchasing Ethereum? I've noticed that the crypto market seems to have certain patterns and cycles, and I'm trying to figure out if there's an optimal time to make my investment. Could it be during certain hours of the day, when trading volume is typically higher or lower? Or perhaps there's a specific day of the week that tends to offer better prices? I'm new to this and would appreciate any insights you could share.
