I could not find any information on how to get the forked coins. I have some ETH in my Mew wallet but I do not see any other coins in there. Any information regarding that?
There's no new fork coin created after the said hard fork made by ETH. There were debates before that it shouldn't be called hard fork but should be replaced as 'network upgrade' because that's the sole purpose of this hard fork.
And we're into that understand that when there's a hardfork, we all think about new coin creation. But on this case, there's no need to worry about it and there's nothing to claim with this Constantinople hard fork.
After the update, based on the price of ETH at that time I will consider investing in Ethereum. But I think that I will remain to invest in ETH and hold it for the end of this year to expect for the improvement of this market because now the price is stable and ready to pump.
Just invest to ethereum if you think it's future will be great, after the fork I have not seen any significant effect to its price.
