Can I use Changelly in the US?

Hello there, I'm curious about using Changelly for my cryptocurrency transactions. I'm located in the United States, so my question is: Can I safely and legally use Changelly for exchanging my digital currencies here in the US? Are there any restrictions or limitations I should be aware of before proceeding? Additionally, are there any alternative platforms you would recommend for US-based users? I appreciate any insights you can provide.
