a number of new tokens that appeared on the market whose prices were far from the initial price they sold (ICO / IEO) even projects that raised funds around 50 million USD the price went up for a moment (flash pump) after that fell to the bottom
Price is an indicator, but it needs to be considered alongside volume, particularly for new coins. This is why marketcap can be so misleading.
Scenario:
There is a new coin that raises $10m at ICO, and there are 10m coins in circulation.
There is zero trading volume on the coin.
I buy 1 coin for $10.
The coin instantly has a marketcap (latest trading price*number of coins) of $10*10m coins =$100m
... which is absurd, and clearly misleading. There's no way their project has suddenly become worth x10 what it was a moment ago, purely on the basis of one person putting $10 into it.
If you see huge price volatility, it can mean that a large number of people are buying up large quantities of the coin, but equally it can mean that one person has made one small order. Always always look at volume.
