I think there is no need for newbies to start investing after knowing everything. Just knowing how to buy and hold bitcoins, you can start holding bitcoins. You don't need to know everything about bitcoin right now, you just need to buy now and start with safety. And then you slowly get to know everything about Bitcoin.
But with this you will be someone who is naive because in the end when only buying bitcoin and holding bitcoin without knowing the basic science of what bitcoin is the same as buying an item which is locked in a chest without knowing what is in the chest.
We must know what we are buying, the benefits we will get and the risks when we buy anything. Likewise with bitcoin when we buy bitcoin we must know what bitcoin is, its functions and uses as well as our benefits when buying bitcoin for what and the risks we will face like what when we buy and store bitcoin.
Many people feel they are deceived because they buy bitcoin and sell at a loss because they don't know what they are buying and don't want to learn more about what we are buying. That is not the fault of bitcoin but we ourselves are naive because we only follow your hype about bitcoin and follow to buy but do not realize that the risk we have to take is actually very large.
