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?
simply because, alt coins is bit more cheaper in price than bitcoin, they will buy it and sell it when the coin is pumping, they will have a profit when the coin they are bought has a little bit high price when they sell it. buy for a little price then sell it for a higher price.thats it.
