It's not about the price of the tokens. I would like to emphasize that high valued tokens/coins DOES NOT REPRESENT THEY ARE GOOD TECHNOLOGY. Look at the price of their tokens/coins in the market, but they keep failing for the past 2 years and some are just starting up and failed right away before and after their launch with 2 MAJOR PROTOCOL BUGS. I am talking about EOS here, very disappointing.
This is true, because most altcoins when started to get a pair in Bitcoin on exchanges it becomes dependent to it so wherever Bitcoin price goes it will follow it but not all the time, because most altcoins can easily gets manipulated or gets pumped and dumped by group of huge investors. And also it doesn't always mean that when a specific cryptocurrency price is high it is a good choice to invest your money, remember that a coin that have a fix and low supply will always have a huge value. We should always have to look at the development and the purpose of those coins or if there is really a chance of good future for it before you invest on it.
