And here I am, with not even a full four years in the forum!

I'd highly recommend you to read a little bit of what has changed since then. You might feel as if you've been in a comma for a very long time. For example, Multibit is deprecated, absolutely avoid using it. Your best course would be to move to Electrum, as it's probably the only SPV wallet software that has survived since then.
It's so much more complicated now. It was prohibitively complicated for non tech savy people 10 years ago but now I'm not surprised people are scared to get involved and opt for easy closed source solutions that ultimately end up in them being rugged.
Actually, it's much less complicated now. You simply have to write down a seed phrase. Ten years ago, you'd have to either write down a WIF (which is prone to error) or store a wallet file with hands crossed for file corruption.
