Krypto is a Superhero dog from DC Comics.....
To be fair when you type in Krypto the 5th result is Crypto .com, but the majority of the first few pages on Google is about the dog.
There is a company called Krypto in the space that raised a few million a couple of years back....using LetsKrypto .com (awful domain) - interestingly Lets Crypto .com is up for sale at 69k on Sedo
Their App is called Krypto ^
Plus a security system company in Cyprus using Krypto . com.cy
I don't like mixing brandable spellings with other words or mixing 2 different languages - very confusing
Krypto on it's own would be very nice, but adding "invest" in front of it doesn't look good (to me anyway), same as the above using "lets" in front of Krypto
Another thing it's so easy to type in crypto instead of krypto - I did it a few times myself while typing.....
I suppose if you price it fairly someone might bite but overall not the greatest domain.....
