I think bitcoin also need altcoin to foster price. Well, to buy altcoin, or distribute bitcoin, sometimes it takes a bitcoin, so, people need to form altcoin bitcoin, and bitcoin it makes the price to rise. Well, now very much a project and of course it affects the price of bitcoin.Most of the altcoins claim that they bring new things that makes them different from the bitcoin, but in my point of viewthey are all trying to be just copy cats, they are trying to make profit from the successful idea that people liked in bitcoin, except a couple cons here and there they are not really worthwhile coins and some of them dies fast because they don’t have the same user base as the bitcoin.
