Yes. That is one of the key principles, that will help you make profit in any kind of cryptocurrency or asset. This is especially when you automate your trading to buy and sell, maximizing your chances of success in the long term.
I usually try to invest on pump and dump coins for this matter, as they turn out to become profitable over time. Not all of them are ideal, but there are some alts which have a constant price movement, making it ideal for this task.
Nevertheless, as with any investment, always proceed with caution before making any decision. Just my thoughts.
