What's the best way to pay an online merchant using Crypto for someone who has never bought/used it before?

I trust the provider, and it's a small amount I'm willing to risk. Just don't want to throw it away, be frustrated, or get involved with shady people.

Android/Windows user, btw.

Late Edit: for those people who are wondering why I would ask Lemmy strangers about my money decisions, let me tell you my thinking.

I am in the decision making process. One of the things I do when making decisions is gather information from a variety of sources. I then weigh that information as to how useful I find it, research any possible leads, and use it as a launching point for my own investigation. I find that beats the hell out of googling whatever I can think up on my own in a field where I have no experience whatsoever.

For clarification, I'm not telling anyone else how to do anything. You humans live your life however you want, and I respect you as individuals with opinions of your own. Live how you want to live, choose how you want to choose, be how you want to be.

Much peace to all ✌️
