I think the best strategy is to starts with a small amount of money. Buy when the price dips and sell when the price increases. As you gain experience invest more.
that will be my starting game too.
A lot of people keep making this huge mistake and looking only for dips and watching out for when the increase will come. You need to know what you are doing, and also analyze chats. Even at dips, you need to wait for the right moment to get in because what you are looking at as dip, may not even be the last moment of dip yet.
Learn, learn and learn even if you want to start with small and stop thinking you can gain the experience by just starting and then learn from it.
Trading requires your time – most of your day, in fact. Don’t consider it as an option if you have limited hours to spare. The process requires a trader to track the markets and spot opportunities, which can arise any time during the trading hours. Assess how much capital you're willing to risk on each trade (most successful day traders risk less than 1-2% of their account per trade). Set aside a surplus amount of funds that you can trade with and are prepared to lose (which may not happen) while keeping money for your basic living, expenses, etc.
Besides from what you have said. It needs to have an extensive knowledge on how to market runs. One must be able to study and master the trading in order to be successful in trading.
