I was able to go through few books about bitcoin, articles and links sent here as guide in the forum. One of the best, I have come across is learnmeabitcoin.com. I don’t know if there is any easier one to learn from and understand than this. After all this, I am still yet to understand the concept of open/closed wallet, software/hardware wallet, online/offline wallet. I keep getting them mixed up whenever I try to have a grasp of them.
