Don't get wrecked with a promising look of coins coz it will just only rip off your funds. You are looking for mid-term trading coins? Honestly, I'm afraid if you just end up holding long-term, not trading.

Anyways,
In your position, I know that you are not yet familiar with the market. To tell you that trading is risky and what @tvplus006 said was right, you should not get into the thing if you are not ready. I suggest not to look at the price of the coin instead to look at its trading volume as I believe this will measure how a certain project has been valued by the investors and traders. And it is literally saying that there is a strong movement which is a good indication for a better trade.
