Where to invest in crypto with company profits?

I’d like to invest in cryptocurrencies with accumulated profits in a company in fiat (not with personal funds).
The company is incorporated in Estonia.

Do you know any reliable and secure fiat-crypto exchange that can be easily used? Coinbase is a non-go for companies at this point.

I run otc services. It depends on volume only trade significant amounts. Message me on wickr-
