Historically, only 40% of cryptocurrencies have gained value since their initial listing price.
"The blog called Market Sentiment extracted the daily trading data across 317 different exchanges in almost 2,000 different coins to find the commonalities of the best returning cryptocurrencies based on historic price, market capital, and trading volume dating all the way back to December of 2013. And what he found was really surprising. On the surface, it was found that when you compared the first listing price of an exchange with the latest trading price available, only 40% of them gained value."
