Maybe your first few months into your accumulation might not follow the best order and you might probably not buy at the best rate or with the right amount but the reality is that you learn more by doing rather than wishing or making multiple plans that end up not being executed. Like boss JJG rightly said, it's not a complex thing as some people are taking it, you just have to start somewhere even though it's as low as $10 or $100 depending on what's convenient for you. Thier is this feeling that's associated with seeing real result which will help you accumulate more. As long as you've started already, thier is a high probability that you will likely accumulate more but if you're yet to start, then it's almost certain that you will have to wait much longer thierby putting yourself in a position where you will possibly buy at a higher price than you should have bought it if you hard started earlier.
People may doubt on something they want to get in since at first they don't have knowledge about investing on bitcoin since this is new to them but once they got a lot of experience and learnings about what's better investment for them for sure that they will find holding is more better since they would compare all the losses they get from frequent trading than by just holding itself. Also for sure they would learn that its not stressful to execute this type of investment so for sure that once they learn and experience the worst on their early part of trying to earn with bitcoin they could figure out that holding is more better whatever figures they put for long term purposes.
All those who come to invest in cryptocurrency (BTC) invest their capital by analisis the market,whatever you call trading and long term. The BTC market is a bit more volatile so it may take some time to understand but most investors are very skilled.
It is doubtful that there are any precedents for bad experiences in terms of bitcoin. As far as I know no one has suffered from short term investments in bitcoin. If someone is in too much of a hurry, it's a different matter. In the long run Bitcoin gives you greater protection of your principal. On the other hand short-term investing can cause your nerves to fray every moment. So everyone wants to protect themselves first.
