The above picture is correct, it is not as easy as we think, we think we will buy Bitcoin and hold it. But past history shows that holding Bitcoin has to face various problems, as shown in the picture above. But if we have a long-term mindset, then holding Bitcoin will be like a straight road. On the other hand, if we have a short-term plan, then it will seem like a winding road, which will not be possible for us to hold for a long time. So everyone can invest but not everyone can hold for a long time. So if we want to invest in Bitcoin, we have to make a long-term plan, which will bring success in the future.
Holding Bitcoin for long term is not easy but only those that are determined can actually do that and long term is where all the good things one seek from Bitcoin lies. You seems to contradict something, having a long term plan doesn't mean everything will go straight for that investor rather you will have to work everything out yourself remember Bitcoin investment is not all rosey and knowing this will help guide an investor sometimes especially when they come across any temporary challenge.
