The price of bitcoin suffers variations among brokerages, and this variation is an opportunity for you to make money trading, but often, calculating rates to ensure profits can be a rather complex and time-consuming task.
I agree that trading is not for everyone. Many people are busy with their daily lives and cant get enough time or patience to watch and keep tabs on the market for making trades. Most of the professional traders do control their emotions very well. If you cant control your emotions then you should not trade at all in the first place. Using skills to earn, like working for earning is good and is for those who have skills and knowledge in some professional field.
I think just holding bitcoin is not worth it. If you have a huge daily earnings and dont need any side earnings then it might be good. Otherwise I think saving all your bitcoin and holding them is a loss. Surely you wont lose them you wont earn much beyond a limit even after a decade if you had traded that amount frequently. Investing about 50-60% of the coins is enough for common people.
