everyone is talking alts day, but popular altcoin hasn't been pumped yet,
look at Ethereum prices, Ripple, it's still very low, is this alts day?
The alts day will come after a strong Bitcoin growth, alts alone will not grow, because they need some reason to grow, and the best reason to grow is the Bitcoin price.
Bitcoin can't always be considered as the measurements for altcoin about when altcoin coin day has come before. Altcoin can grow even without the help from bitcoin as long as that gives a solid development and good result.
Mass adoption will come for a solid platform with a useful product.
