Most of us want to be rich quick but there's no shortcut to be one even in an illegal way but if you want to be a skilled trader then cryptocurrency is best for you.
For me trading is one of the consideration as short-term because you wanna earn more money in a short period of time.
Long-term is my choice that's why I'm holding my coins as long as I can so that in time for emergencies, I could turn my coins into money no matter how much value they have.
