It's important to find what investment is going to be relevant and worthy in 2-3 years. Maybe you will reevaluate your decision once in a while. But it will come to your analysis, and understanding of what to pick in the beginning how to adjust in time.

Like any other investment there is no loss until you sell. Assuming the investor has done their due diligence and has invested based on fundamentals there is nothing about these types of market movements (coordinated dumping by whales) that alters the fundamentals behind the original investment. Ie. you don't sell because some rich jerks are pushing price around for their benefit.

Well said.
