Where to invest (in Luna) for a US business (as a foreigner)

Hi, I'm a Polish resident with a European passport with an American business.

I intend to invest some profits of my American business in crypto and I want to know which is the best/ideal platform to invest at.

I have a private Binance account in Poland and I'm able to invest without any issues but I've read that Binance multi-sub account isn't working anymore or only for tier 1 businesses type, regardless, I've read that using a VPN for registration to the binanace.su.com is an option but there are some risks of getting the hammer ban if used incorrectly (i.e using your phone to log in with a local mobile carrier that will alarm the platform you're located elsewhere).

I wanted to know which crypto platform can I sign in to as an American business from another country.

FYI - I'm an investor and not a trader so it should be a set and forget.
