This is bordering on the technical but I still have no idea how transcations are processed. The only vague idea I have about it is that the transactions are somehow "queued" and the miners prioritize the one with larger transaction fees. This is why up to this point I'm still using online wallets. I'm starting to read about software wallets (I'll probably never get to the point of having to buy the hardware one), just in case I'd need to switch to those.
Hardest thing to understand when I first got introduced into this whole Bitcoin thing was how addresses / wallets worked. Not in the sense that I didn't know to operate them, but in how they operated and why they operated in such ways. (Paper wallets / QR codes / Also even the Blockchain : those kind of stuff always made me curious)
:: My easing into Bitcoin wasn't that rough and actually was quite smooth even invigorating that I can finally now partake in online activities without the need for a credit card. However easy it was getting INTO it, understanding it was a whole other thing.
Oh yes! I'm already using my online wallet to load my phone credits but still have little idea on how the transactions actually operate.
