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.
If you don't used altcoin as a form of crypto-currency in trading is just a waste of opportunity. Because just like Bitcoin it has system and it might have a big development on its price, transaction and security in the future. The opportunity is quite wide and rigid to altcoin because it much used on trading so its price moves and increase at the same time and it is the best prospect for trading and investment. Do not limit yourself hence continue on having options for you to earn more.
