Perhaps one of the most frequent problems that people have is a kind of failure to invest that goes along with a kind of eagerness to either take out profits from time to time and/or failure to keep investing in order to be able to enjoy some of the benefits of compounding, which many of us likely realize that the compounding has exponential aspects that fold upon themselves, but still are likely to take more than just a few years to play out.. so compounding gets bigger and Bigger and BIGGER .. so the first few times that you might get a doubling of your investment portfolio (whether in nominal terms or in real terms) might feel good but then when such doubling comes down the road later, the amounts can become somewhat staggering, especially if you might have had several doublings stacked on top of each other.. and the mind becomes somewhat unable to recognize and appreciate how those amounts had ended up growing so much even though they might have had started out with ongoing small, persistent and consistent contributions that might not even have had been very noticeable while they were taking place in the earlier stages of the investment... so there are a lot of occasions that people will pull out way too much of their value from their investment(s) - whether BTC or otherwise - and pull out their principle too early and thereafter fail to experience the various doublings (or the exponential/compounding aspects of their investments)...  

so that is the problem with failing to invest enough..

So, even though I agree that the principles of getting richie are easy peasy... but the actual ongoing, persistent and consistent putting them to into practice and tailoring them to individual circumstances is not as easy as you seem to be suggesting them to be.... even guys (and gals) who have been attempting to employ well-balanced practices for years can get themselves into pickle situations - and sometimes these same experienced folks miscalculate the employment of sound strategies may well have to do with figuring out position size rather than all or nothing kind of thinking... especially when it comes to something like bitcoin that some folks might give a thumbs up or a thumbs down, and perhaps there might be some kind of need to still invest at least 1% even with a thumbs down view of bitcoin, and even with a thumbs up viewpoint there still might be a need to make sure not to invest more than 25% into bitcoin, and I am not even going to claim to know what any individual's position size should be, even if my feelings are somewhat strong about getting off zero  and even if I am o.k. with starting out by telling a newbie to consider between 1% to 25% to be a prudent/reasonable starting point for their BTC investment, and in the end they are responsible for figuring within that range where their situation might dictate that they should be allocating and how they are going to manage building their position over time, how long it will take to build their initial position and then try to employ  maintenance once they have accumulated and reached their target levels - and of course, trying to keep learning along the way, too...
