This post is not only for investors who want in trading. This post is for all of us. When you have a Bitcoin you need to convert it to USD and when you have also other currency like Ethereum you need also to convert it to USD. Then now you don't know how the Price going, and you convert it in a Downtrend then after an hour it goes Uptrend 5X or more than your exchange few hours ago its so sad  right?
