Why is it so hard to create an email account?

Today I wanted to create a new email account that I will use specifically for info on cryptocurrency and I spent a good hour on finding a name that resonates with me. But of course, every name I wanted was taken. Don't you sometimes wonder how many email addresses have been created? I myself have 3. One ends with Hive account@rocketmail.com. one with Hive account@gmail.com and one with Hive account@icloud.com. Does anyone have any good tips on creating the email of my dreams? Just kidding. I just want something meaningful that's not hard to remember. Thank you in advance for all your help.
