Another thing I consider dangerous which many little investors do is to be jealous of those who started when the price was far cheaper or those who have big capital to invest into Bitcoin. The amount does not matter so long as we are intentional and focused on the bigger picture which is continuously accumulating Bitcoin and holding it for several year, it will surely get bigger and better.
Frequently people cannot help themselves from comparing, and maybe some of that can be healthy... but yeah, there needs to be some of your own personal actions that may well have good chances of surpassing a lot of peers who do not seem to have much if any clue about bitcoin, even though there are a lot of folks who have heard the word bitcoin and they think that they know what it means, but they likely do not, so even if you are not able to invest a lot of money, when they finanlly figure out bitcoin 4-10 years later, you are going to have a pretty good head start on them, and they will wonder how you got so many bitcoin (or should I say satoshis) and maybe you will have 0.21 bitcoin (or 21 million satoshis) and they are struggling to get 1 million satoshis.
