currently there are many ICO-generated altcoins available on the exchange, and usually when they enter the market the price will drop dramatically and below the ICO price, I personally often take advantage of the situation. but this is also not easy, because it must analyze it first. whether the ICO is a success, look at the total supply to consider a reasonable price, and many other analyzes. Nothing is easy to achieve a profit.

The idea behind trading is very simple, you just buy low and sell high. You clearly don't know anything for sure but to predict, you just need to follow the news regarding that specific coin (a hard fork, an update, being added to an exchange, merchants accepting it etc.) all these factors play a big role in determining the price. Another way would be to buy CryptoPing BOT subscription, It has the ability to predict based on the increase on volume etc.
