I think that a lot of what you are suggesting relates to managing bitcoin position size, and the skills and/or the knowledge of the risks do not need to be known in advance in order for anyone to get started investing into bitcoin. Anyone should be able to get started investing into bitcoin with the ONLY criteria being that they have a discretionary income, and the more uncertain or scared they are about investing into bitcoin, then the more of a whimpy start that they would take and the more confident and/or bullish they are, then the more aggressive that they would be, and they can learn how to go from being whimpy to being aggressive as they are figuring out how to make sure that they have good cashflow management systems in place.
That is interesting perspective on getting started with Bitcoin investing.
You are saying that to start investing in Bitcoin we only need money we can afford to lose and we do not need to know about risks or how much to invest upfront. Your idea is good that people can start small if they are nervous and then invest more aggressively as they learn to manage their money.
While it is good to learn by doing and start small many people would say it is really important to understand risks and how much Bitcoin price can change before we begin. And when we start with small investment we will learn slowly and understand that how market move and also calculate the right time to buy. Sticking on plan is really important means we should never forget the strategy which we have started in the early stage. It can be changed with the passage of time but if this is still working good so we should stick on it.
