There are currently at least 1,200 different types of coins as listed on Coinmarketcap. Which one will prevail? Or rather, which group of coins will survive for the long term. What coin/token should you have now for the year 2019?
Top 10 coins/tokens in coinmarketcap will survive for sure, maybe all top 100 tokens too.
Don't forget that some already dead projects were in top 10 in the past.
