In short term trading the pros is the high possibility of profits if you focus on it and have plenty of time monitoring the movement of prices on other hand the consequences is the high risk in doing so because in a matter of seconds the price can turn into lowest to highest. I do a long term one as Im not a risk taker and I have much patience to wait for months or even years.
In my opinion, this can increase the efficiency of capital operation and put funds in a highly flexible state of operation, which not only avoids the funds being put on hold but also makes the funds have unexpected utility.
