UX-wise, as other said, I think it makes sense to ask for the CC as late in the process as possible: you will make your most valuable user understand how great your platform is.

Also, I think that for a platform such as yours, credit cards are absolutely a must. The risk in opening it to scammers (mining, torrent seeds, etc) is just to high; I remember reading this from fly.io [0] that explains the pain in reducing fraud.
