it all depends on how desired investment. if you invest long term, you will wait for a very high price, but if you want to trade or invest with day trade, of course you will sell the coins at any time even though the profit is very little.
You are right. It all depends on the type of investment desired, long term or short term. The market is not yet fully conducive, there are still many pitfalls that make in-depth analysis even chaotic. Especially the influence of news and rumours. I tend to choose short-term investments, day trading. If there is a good opportunity then enter the exchange, take profit, even if it's small, it's okay, hit and run.
