for me I think the altcoins that will be greener within this year will be Polygon, Solana, Terra and most especially XRP knowing that XRP is the only top rank crypto that haven't reached its ATH yet. In addition, I think Metaverse token will also bleed green as well.
I think you miss understood what the op are saying here. What green he mean is not about the value of the crypto or when the crypto rise in price but it is if which crypto is more friendly to the environment. I am not familiar if what are the mechanism of the coins that you mentioned above or if they work the same with bitcoin therefore I am going to pick on the OP's list.
Chia and Nano are the coins that I heard on the news and they say that these coins are greener that bitcoin. The other one from his choice would be bitgreen although I did not hear this coin before but its name says it all right? So, I assume that it was greener than in bitcoin.
