Before you start trading, better to know what do you prefer, short, mid or long term trading so you'll know what coin to buy. Hence, don't expect that return will be quick and anticipate rough roads along the way.
I would rather advice to invest altcoin and hold it for a couple of months. The cryptocurrency price for this year is not good to perform a day or short trading. Most of the time price move down and it takes several weeks to pump up with just a little amount of increase.
If you're a beginner, it's better to focus in buying more bitcoin and less than altcoins as the movement of altcoins are inconsistent and just living in hype nevertheless don't trust those hype.
