Well, thats really a tough thing to answer. It seems lately even alot of the 'good' coins are dying out or losing community support.
I don't follow the altcoins much anymore. They attained their hour of fame, made a few people wealthy, made a lot of people poorer. People lost interest and those who got burned left the scene.
I rarely see an altcoin listed as a payment option. I do see bitcoin.
Are there any altcoin communities/developers actively pounding on doors trying to get their coin accepted by business? They lose interest after they sell a few million coins.
Instead, they build a new coin with bigger and better promises hoping people will flock to buy.
Altcoin is much more used in the field of trading so if people's decide to buy Altcoin it could be better if they we look it as a form of trading. And i agree that most altcoin is not accepted on transaction yet is quite need development. It is matter of time and support of people's to used it on a daily transaction through trading. And if you want to know the trend of a specific Altcoin you must read some ICO projects so you could know if it is worth buying and worth for trading.
