People's refer Bitcoin as game, we understand that it dynamic and also unpredictable like gambling, but that doesn't mean we can compare the Bitcoin gambling, because even those that are the Bitcoin to that gambling there have never introduced themselves into the Bitcoin investment, if not they will never put a gambling on their mindset.
Financial games and gambling are two completely different fields, investing in stocks and real estate is also called financial games. If someone compares investing with gambling, it only proves they know nothing about investing and are only making comparisons based on their short-sighted thinking.
Furlthermore, Bitcoin is something that brings a better outcome that means if the person have a patient and hold it for a long period of time, since as people's say it that's how it goes Bitcoin is unpredictable as we can now that the market is flotrating but with that anybody that purchase a Bitcoin now and wait for ATH it will get huge profits in future.
Not only bitcoin, in any financial game there will be winners and losers, and it will all depend on each person's ability. Bitcoin is a highly profitable investment but that doesn't mean anyone who invests in it will make a profit, financial markets don't work like that. If you want to sell at a high price and take a profit, you needs someone to buy bitcoin at a high price and they will most likely be the ones who lose money.
