There are a lot of altcoins and I am really curious why people buy them. Is there any worth of altcoin? Why not using only bitcoin? What's the future of altcoins?
That's why there is trading and in crypto currency it's like a foreign exchange and made it even possible. But that's the only decision that you need to do, choose the best alt coins and wait for the right time to makes it value higher. There are people that are not only depending with bitcoin because they wanted to try something new and alt coins are the alternative for it.
