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.
If you are a newbie, you don't need to know everything immediately. When i started, i was hacked, as many others.
Maybe it's not the best way but if you have under 1000$ in any crypto, i'd say to keep or buy them on binance/coinbase.
Why? Because those 2 are the most trusted, just turn on every 2FA they have and don't brag about it.
If you want more advanced security, find some tutorial how to make wallet safely, there are a lot of walkthroughs to do it.
I think other members explained everything so you should be good.
