Relying on the technical analysis of price charts. Following the market news from the trusted sources so that you can take precaution when needed. Trying to improve your trading knowledge my making practise. All would help you a lot.
Research would be the best medium to understand how the price increase and decrease of the coins. Basic information would be the coins road map for the development of each coins. Trading would be be difficult if you dont do this.
