is it true is altcoin? if true I think it will not have a big impact for crypto itself instead. but I'm still curious, let's wait
yes, "bitcoin gold" is an altcoin which is also going to change how the mining of bitcoin works so that it can be mined with GPU. if you ask me that is a futile effort but it may be interesting to see how it is really going to work.
and don't forget that BTG has a huge premine which they are calling "ICO" for some weird reason!
