Trading is knife with two edges. As long as you know what are you are doing, it could be a very good strategy to multiply BTC. However, you need to investigate carefully the alt in which you are entering. Timing is essential - buy at the dip not at the peak is a must. Last but not least you need to convert your profit, not to wait too much because you could get greedy and the coin may return to the original state and never come back. The truth is you need experience which will you have with time.
