Forget Mycelium, I will just import those keys into Electrum but even then how will I be able to run the Electrum Server ?
I tried to search it on google but the whole process seems to have so many steps.
It's a tough procedure if you're not used to it. I had made a thread few months ago:
[Questions] Running my own electrum serverGenerally, you'll have to run a Bitcoin node (full or pruned) and install Chris Belcher's
EPS (Electrum Personal Server). I had tried it and it works like a charm, but it doesn't work if you want it to be public.
You'll have to install
ElectrumX if you want to be part of the electrum network, which is an even tougher process.
