Cardano is the best third generation altcoin, in terms of technology. And that justifies it's position as the 5th largest cryptocurrency and the market cap of >$50 billion. But in terms of acceptability, Cardano is lagging behind some of the smaller altcoins such as Litecoin and Bitcoin Cash. Despite the advanced features, the developers haven't succeeded in making this coin very user friendly. They need to learn from coins such as Litecoin, which are really user friendly. We need to remember that less tech savvy users also need to use cryptocurrency.
