Well, your points are not actually bad but the most important knowledge that a new Bitcoin investor needs before applying security to his holdings is how to buy. If an investor knows how to buy he can also know how to secure his Bitcoin, at that moment he believes that it is his asset because he exchanged his fiat for Bitcoin through p2p, at this first point when he has purchased Bitcoin he doesn't care if he has make profits or not, the next step is for him to send the Bitcoin to the wallet he will use for holding. Which means after buying, the other important step is sending.
As a newbie to Bitcoin investment, you also need to calculate the figures of Bitcoin you have, so that while sending from the exchange you bought Bitcoin from to the wallet that you will use for holding you can be able to figure out the fees for your transactions so that you will know the figures of Bitcoin that you will receive.
Not quite
In Engineering there's a saying in my side that before learning how to switch ON a machine learn how to switch it Off first
There are people, I mean lots of people that can buy and sell Bitcoin but few of the majority can really secure their holdings
Like we normally say if it ain't your keys, it ain't your coins.
What am saying is even if you can buy and sell Bitcoin with no prior knowledge on how to secure it
Good wallets to use among other security measures
It's the same as placing your money in an empty pockets
The importance of security is quite underrated
Personally I feel a newbie should learn about a secure wallet and method to implement
Before learning how to buy or sell.
For me I would say it is important to study about security measures before investing in Bitcoin, but it doesn't mean that one should apply for online or offline course to only study much about security measures and how to buy and sell bitcoin before starting to invest.
