What should I consider for a SaaS or Software platform accepting crypto payments

Hello guys.

I am currently thinking about accepting crypto on my platform and I also am thinking about "crypto only" payments for the website.

I even talked to a local company who provides payment gateways and they let us accept currencies such as BTC, ETH and USDT (I know they have a few more options but I'm not sure which were they, maybe TRX or SOL).

Now, my question is that what should I consider when I offer a crypto-only payment system? You may have guessed it, my main problem is the customer's trust specially with all these scams in the crypto space.
