I did some research, therefore i want to share with you a great tip,which can help you better succeed if you want to invest in your favourite altcoins.First of all,this tip is not available for coins which recently hit the exchange markets!!! Secondly, you should always check the coinmarketcap to see the trading volume for the altcoins you want to invest in ( there is a section -Biggest Gainers and Losers), if the trade volume (24 h) is at least 500.000 $ it is already a good sign, this means that people are interested in the services offered by the company. Have fun investing!
