I have started playing around with sending transactions. In one case, a transaction was accepted but never confirms. If I try to submit it again, I get duplicate transaction error, so I know it is in the mempool.
I also have a HODL test transaction that is being refused by the network, which means something is broken in the mining code.
My Bitcoin Cash stuff all works okay. So with BTG being broken and BCH not broken, I would bet on BCH.
The devs of Bitcoin Gold definitely need to get hat sorted out and to work even harder on their coin, otherwhise it can't compete with the reallly big and successfull cryptos. Currently, it's only the name that keeps BTG Gold over water and maybe the mining with GPUs
It doesn't make a change for me. Bitcoin shouldn't be mined with GUP type equipments and anything that makes this possible is considered as a standard altcoin. By using name bitcoin, they only aim to fool people.
