It is not easy for about newbie to have the technical knowledge of bitcoin in few months because it is broad an d irrelevant for them if not it will prevent/scare them away from investing in bitcoin. During the time that you are busy trying to learn the technical analysis, the price of bitcoin is increasing and you are missing the opportunity of filling up your stash by buying right away when you have the money and have figured out how much from you disposable will enable you invest amd hodli for long.
If you look at the early people who didn't buy bitcoin then due to some excuses they came up with at that time are regretting it now and some people that also thought it needs too much knowledge to invest and didn't invest are also regretting it. Just the way you save money in the bank every time you receive your pay for an important achievement in future so that the money can reach the expected amount is the same way that you will channel that money into bitcoin instead of your bank.
I agree with you about the learning and filling the stash, Bitcoin price movement is something that doesn't wait for no one give a clue that this is when I'm going high or low, the moment you have that opportunity to get involved you do it because by the time you say you're ready to do whatever, the price might have gone beyond your funds and you start regroup again, is best to do it when you have the chance and you can fill in first and later go back to learn the technical analysis to expand your knowledge but when you say you have to learn first before buying then is on you if the price sky rocket, no matter how small you get started to avoid had I know.
Sometimes we don't need much to even motivate us to start something, is best to do it and ask questions later after all life it self is a risk, everything we do is a risk, is just for us to choose the line of risk we want to put ourselves into. Bitcoin investment is a very lucrative business and there are risk involved so is up to you if you want to come into it or not. If we have to wait till is time, then that time might be the wrong time to even invest and for me to be on the safer side as a newbie is to start small as long as you can achieve your goal then you're good to go, with time you double it up when you're buy.
