I have heard of such services before (not this website specifically, but similar ones) and they seem like a good idea because, how can you be sure of the legality of the coins you receive otherwise?
But what makes me raise my eyebrow is the fact that these services are usually free. If they don't charge you for their work, then they must be making profit otherwise, probably with your data.
Someone with experience can shed some light on the safety of using these services?
You’ve hit on a crucial point that many crypto users grapple with: the seemingly paradoxical nature of “free” services in the digital world, especially when it comes to sensitive data like transaction history. Your skepticism is completely valid, and it’s essential to approach these services with a critical eye.
