Getting any domain with the word "crypto" in it that doesn't sound forced is going to be impossible. I've tried. If you want a domain that sounds good and brandable but you can't afford a higher priced domain, I would try switching out the word "crypto" for something else that means or implies the same thing. Like "coin" or something. But even "coin" is going to be tough. The people who buy and sell domains were all over the crypto niche from day one and it shows.
As someone who is a bit obsessed with domains and brand names, I don't think either of your domain choices sound like they make a lot of sense. But then again, your website doesn't need to be perfect to make a lot of money and neither does your name. But if your name isn't going to make sense, I would go with an invented word or an animal or a color or something instead of words that imply specific things that your website doesn't deliver on. Unless you're literally going to make a website about experimental crypto, which I doubt.
