What advantages do altcoins have that differs it from bitcoin ?
For me, alt coins have a lot of advantages compared to bitcoins mainly, the use, the price, and the features per token. There are countless amount of alt coins out there that are way more useful than bitcoins and most of them are cheap. The features, on the other hand, are no joke. Alt coins are pretty meaty when it comes to features.
I think it is still a really good platform that brings a lot of innovation to the market, the thing is that most people are focusing in it's monetary value for trading, and with a lot of altcoins coming out every day, ethereum keeps dropping in value because there is more competition.
