I have never heard trading to be easy but you may profit handsomely if you are able to invest wisely.
It is good to research first before making an investment and choosing a coin. There are some coins out there that are good and ideal for short term or long term trading. Most look into the dev team, whitepaper and popularity of an ICO to determine the success of the coin or project. Some look into the reviews or reactions from the other altcoin buyers. Just be very wary because some scams have professional looking ICOs and are very enticing. From these, you will be able to tell the potential of a coin.
If it is as easy as that then we all would have been making some pretty good profit. Choosing a good coin to invest is all about the team, the project that makes the coin tick and how well people are going to utilize that which of course creates demand is what makes a good coin.
Lots of ICOs today do not even have a product, with some wacky team and people just invest their money. How do they expect not to get scammed or invest in a shitty coin?
