There are many ways you can improve your trading.

I think the most important thing you need to do if you want to make profit is do research before investing in a coin.

If you are well informed about recent events you will be able to predict possible movements of the market.

Personally I focus on reading articles and attending to crypto meetup when I have time.

Also when day trading I use some free software that predicts future movements of several coins. www.cryptoforesight.org

Trading will always be unpredictable, but If you are informed you will have less risk of losing money.

Never give up trading as you will learn something new every day!
