I am asking this because not everyone has made tangible profit for holding. Just like myself I end up selling at a loss most times just to solve a problem.
There seems to be something wrong with the way you understand holding and it should not lead you to losses when holding is executed correctly. One thing that I think makes you lose and that is influenced by downward price pressure which makes you panic and sell. That doesn't solve the problem but you create your own problems because you don't try to wait for the price increase in the next period and if you understand the bitcoin cycle then that doesn't need to happen.
Some might be lucky to buy at a low rate and within few weeks or months the price just pumps to their favour. This kept me wondering if Bitcoin is actually for every one or it is a scheme for selected individuals.
It is closer to short-term trading and market analysis skills are needed if you take such positions. Otherwise price fluctuations can take you to the same stage of loss and that is why understand investment first before taking a chance in it. Bitcoin is for everyone but not everyone understands how to invest and trade properly and that is why some people experience unnecessary losses.
