Someone say yes someone say no. Explain me in scientific way. yes or no?
I think you can't get the exact answer anywhere because the main reason is the definition which is saying the coins except from the bitcoin are known as altcoin .
Here the official announcement said that the network of the bcc coin is totally independent from bitcoin network , so here we can say it is altcoin .
But still here we are getting this coin from the bitcoin network ( phrase backup , private key etc ) so here directly from the btc , so here in this case we can't say it altcoin .
But here my opinion direct telling that bcc is altcoin only .
Well it is altcoin or not doesn't a matter for us because the future will tell us that with which coin we will go and why and will make the king that coin and other of them will become altcoin .
