I believe it's not something new that BCH will undergo a hard fork tomorrow which could possibly generate a new coin but there's something I don't understand about the new coin which will be generated and also airdropped in the ratio of 1:1.
I am holding 0.1BCH does that mean I will also get 0.1 of the newly generated coin or the airdrop is not for people that hold at least 1BCH?
It's depend if they receive enough support for the new coins then it's mostlikely you will receive the same amount of new coins.
No idea if there is a minimum requirements that's needed to receive a free coins I only understand is you will receive the same amount once it's deploy.
So far that i know you will get same Amount like your Balance on new Chain (BCH Node), 0.1 BCH = Newly Forked 0.1 BCH, Also what BCH you holding, It's ABC Or SV? After reading it some article if i'm not wrong only People who hold ABC will get new forked Coin. It's was complicated for sure, BCH community have some complex things and i advice don't expect so much from this fork since newly concept was diverting block rewards to Dev Wallet/Team and the community didn't like it.
Even some exchange doenst know what to do with this fork they are stopping any transaction from bch when the fork started .
