Thanks for following!
Yes it seems complicated at first but some things seems necessary to avoid spam, or abuse of the system. Everything seems really well thought. I was learning about bitcoins back in the time and I remember when bitcoin reached parity to the $... I denied it.. thinking this is just an experiment... the blockchain will be huge and I would not have space in the hard drive to have a copy of the blockchain, or the electricity needed to maintain an increasing difficulty seems anti ecological... etc etc... so I denied it and forgot about it. Another mistake in my life. Proof of Brain has opened my eyes again.
