honestly, very bad. a quality domain is simple and short, it is best if it is one word without strange characters in a row. hence the domain of one "short" word is the most valuable.
Your domain has 4 words, billion + blocks + home + page ... almost an essay to write in the search box. you had to be a little more creative here since it is the domain itself 50% of your business idea.
you hurried with domain registration, here you got some suggestions that are better than your choice, but it's not too late for you to change your final decision.
