Ask HN: What crypto do you use for a consumer facing app? Is Ethereum OK?

Use something like Coinbase Commerce and abstract away the need to choose one and just build on top of it

Bitcoin and Ethereum are obviously the two most popular but their fees are often high. Some of the more useable cryptocurrencies for transactions are Nano, Bitcoin Cash and Monero.

Those are just some examples - my point is that what’s popular and what’s a good technical choice are two different things.

If you’re integrating this into an app, include at least a couple of different cryptocurrencies.

You're missing something: sensible transaction speed and ease of currency conversion from usd.

Stablecoins like USDT fits this.

Look into stablecoins or layer 2

Ethereum is the safest bet right now.

Look into Arbitrum, it operates on the Ethereum chain, but has better performance and much lower fees.
