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.
Holding Bitcoin for a long term is not difficult don't make him scared he just need to have a good source of income and have a good investment plan before holding so that he can't be tired along the way, long term or short term is achieved if you make up your mind but holding for long term gives you the assurance of maximizing profit because there is a possibility of a price increase in future and if you are patient enough in your holding you are sure of making more profit. No investment is rosey don't make it seem like Bitcoin investment is different but it is better than most of the other investments out there which is the more reason why you should invest in Bitcoin then any other investment.
