What is the common difference between bitcoin and altcoin ?
Bitcoin is first and famous cryptocurrency, they used sha256 as algorithm. Altcoin is other coin than bitcoin because nowadays bitcoin as standard pair for cryptocurrency, they have various algorithm and mechanism. So if any new coin launched people will also called it as altcoin
Very good explanation,,so If the new coin is always called alticoin, will it be called bitcoin as well?
i don't think so... it is still alternate coin, and that is why it is called ALTERNATE coin because of the reason stated above, but you can sell it to convert into bitcoin. the difference is not only the name of its coin, but its function and uses, and much more is that they par lower than bitcoin's price, there are also alt coins existed that almost within the price of bitcoin but it still varies to the price of bitcoin.
