Can you elaborate though? Is it better (and for what reason), to run Electrum Server upon your node, instead of connecting Sparrow to your node?
No, it's no better or worse. In both cases, all your data will come from your own node rather than that of a third party, and so your privacy will be maintained. If you already have an Electrum server set up, then no reason not to use it.
There are actually too many people that used to use Electrum since it was released and haven't switched to any other alternative. That's what made me curious.
If you are already familiar with Electrum and already have a server set up, then I see no reason to change unless you wanted to use Whirlpool.
It seems I will be better using any of the wallet considering my recent break down with the Mycelium wallet for iOS. It was completely troubling to set up that wallet on iOS since it’s missing few pieces which help us import our back up and/or imported addresses. It’s far better I either keep using hardware wallet or simply get new one like electrum and sparrow.
I will see how it goes with the set up on laptop and doesn’t have lengthy process of set up. :-)
The only thing I need to know is how much space these guys will take up? Is it gonna be entire blockchain that will get synchronised taking up entire disk on my lappy?
