I'm a developer who is building a website that need to process Bitcoin payment requests. So I need a payment gateway.
In my last project, I used Electrum wallet as payment gateway but my last project doesn't have too much bitcoin payment requests, and electrum works fine. But I'm afraid of electrum's limitations and I'm not sure it's a good idea to use electrum when processing lots of payment requests.
Bitcoin Core runs bitcoin node but it takes too much disk space (full node) or CPU usage (prune mode) and I'm afraid it's not a good idea too.
So please tell me which one preforms better as a website's payment gateway, and why. Thank you all for answering.
