Are any of these forks viable, have wallets, and devs, and miners, on exchanges etc
Latest scheduled Monero hard fork changed POW algorithm to break hidden ASICs, ASIC companies and people who paid $12000 for a now useless ASIC forked the chain (4 times).
Only 1 appears to be traded on an exchange.
To be clear there was only one chain fork. There are several different projects all claiming to be the 'official' project representing the old chain.
Haha, true that - I could have made it clearer ... current Monero dev team is very open and transparent about decisions and development; I'm sticking with the Monero (v7) chain
