I remember stumbling into an archive with millions of Bitcoin wallet addresses, I was hoping to see what was gonna be the way forward if the entire wallet addresses had such billboard of display. The funny part of it was that the private keys were against the row in which the public keys were. I thought to myself, "if this is what it is then the space is not what Satoshi created, later I found out that the tech was bigger than a one lane solution.
I took my mind off those sheets and focused on the tech, till today, I have not regretting getting into the tech early enough even though it was late, I consider it still early.
