how many of u agree that the altcoins are the best .......
bcoz it is faster ...it can be used for faster transaction and even the transaction fee is also comparatively less
and even buying an altcoin is cheaper and u can buy more coins ..and earn more profits ...but the coin u choose must be good coin
What about 51% attack probability?

What about the fact that all these coins are more volatile than bitcoin is, and when it is falling down, they do the same but much more dramatically?
