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. 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..
In every thing in life, everyone is not favoured. Be it business, there are people who succeeds in business while others will also fail in the same business. This happens to relate to luck and also knowledge. A good business man will always tend to succeed while a bad business man will always tend to lose money.
This same thing is applicable in your case. Someone who is knowledgeable about bitcoin will always know the right time to buy or sell. The person will also know about halving and its effects. With this little knowledge, thatbwill be difference between you and someone who is knowledgeable.
