This is my experience. Don’t use the site. It might not be a scam in the true sense but it does not work reliably. I lost $20. Well bought $20 of ETH to fund the minting of an NFT, then gave up part of that in transactional fees (as expected) and finally was quoted $10 for the “gas money” fee - which varies by the second… to complete the minting of a digital artwork upload into an NFT… and the process failed, did not complete. Money is gone and there’s nothing to show for it.
Not a huge loss but it’s buggy as hell.
