You have to start small to start trading, for example 10-20 USD is enough to start trading. if the decision you choose is correct then you can already generate 1-5 USD of the increase in coin price you buy, but not easy you have to be good at analyzing coins that will soon rise in price. Once you begin to understand about coin trading, you can use a large capital of 100 USD or more to generate greater profits.
Much wiser for a newbie to start out on small profits rather than on directly using up huge funds on doing trading.For this matter you would only risk a little amount while you are still learning up new things along the way. Common problems or mistakes on some new traders is that they do rush up on things 10-20$ is an ideal try out amount for you to practice on. Be patient on the numbers of orders you do made since it just a small amount and once you see you are profitable then gradually increase capital.
