I still insist that trading should not be really the main purpose of using bitcoin but unfortunately I am talking against a multi-million dollar sector that is run by billion dollar valuation companies so there is really no way I will ever be heard. When you buy and sell bitcoin all that quickly you are using it the wrong way and you are actually hurting yourself as well.
Bitcoin should have been earned/spent instead of bought/sold and that would even increase the price of bitcoin as well and make the traders money but unfortunately it became something for financial corporations to make more profits from the smaller investors and result with poor/middle class people to lose even more money to them. Really a big shame considering it was created just for the opposite reasons.
In fact, people usually only care about profit when trading and no one ventures to invest in the long run because this market is very volatile. In addition, this year the market is likely to become harsher because we cannot predict anything. However, if you have an effective trading strategy and spend a lot of time analyzing the charts, you will find a reasonable price to buy.
I agree, most people want to get profit so they choose to trade than invest, also most of people want to earn easily than waiting to get profit. For me I choose trading because there's a small risk to take as long as have enough knowledge and have strategy.
