Investing in crypto is not as easy as said. This is not only about buying cheap and selling at a higher price. For, we don't know if the price will rise up significantly after we bought the coins or if the coins will dramatically drop again and again.
That is why we need to make certain analyses on what we are going to take, for buying what coins, at what rates, and for what target.
Investing in crypto is a high risk, moreover in altcoins which are new enough. It may be only because of hype so the price rises up very high. However, the price will fall down quickly after the hype is over. This condition is very often happens in the crypto world. That is why we need to analyze what coins to invest seriously and carefully.
