you better don't trade at the first place, because according to your question it can easily be concluded that you have no idea how to trade. Altcoins are extremely volatile which means they are very easily manipulated and their value changes really fast. Someone without a lot of experience might get rekt in an instant, and that is what usually happens. If you want to trade coins why not trade at least BTC or ETH which are relatively more stable, the rest of the altcoins are fluctuating way too much for you to forecast any movement. It's really difficult. Before you get into crypto you could start trading on the FOREX market and make sure you understand first the traditional dynamics and technical analysis before moving to the crypto one's (which are more dangerous).
