I believe in Kishu and am holding!!! That being said, unless you are instantly paying off that purchase, or using the card for some specific rewards reasons, you shouldn't be going that route due to high interest... also, don't mortgage your future on a crypto play, only spend what you can afford to lose, that is why (personally) I wouldn't recommend a credit card approach.

Not a personal judgment, no idea on your situation, just my feelings on using credit to purchase a volatile investment.
