The feeling of investing in Bitcoin with the motive to try luck is for beginners, an informed investors who knows what Bitcoin investing is all about doesn't have such thought. Many investors are making erroneous investment because they believe they can make money so quickly from Bitcoin, they don't understand that making money from Bitcoin requires patience, and proper understanding of the market. Initially when I started Bitcoin investing, because of lack of knowledge I incured losses, and I thought I could make more within a very short period of time.
Investors who understand Bitcoin investing does not try luck, but follows the principles of Bitcoin investing, and eventually make profit on the long run.
Those who really know or understand how Bitcoin works never compare investing in Bitcoin with luck. I think those who basically have little knowledge about Bitcoin can believe in luck because they do not have proper knowledge about Bitcoin. The knowledge they have is enough for the highest luck. They do not know or can not think about Bitcoin, they can only invest for a short time with the aim of getting rich quickly and rely on luck. They do not know or understand that Bitcoin is a long-term investment. Investing with a short-term plan does not have the possibility of profit and there is a lot of risk of losing money. Those who really have knowledge about Bitcoin would never luck through investment, this is the main thing.
