hehe, well I have been in this website since 2013, yeah good traders are well informed about mining because that is where have been the source of the coins, they need to be, trust me, but things have been changing due to pos and that has been bad to the ecosystem, any coin that doesn't need to be mined is bad, look what happened in 2017-2018, icos, none of them needed to be mined, look what happened, it crashed everything, people had no idea about it, they thought icos were like eth or btc and they bought without thinking, mining at least there is a total number of minted coins everyday, with things like defi we have no idea about if billions of coins can be created at whim, so you can't invest on that thing if you dont know where that thing is headed, defi and icos rules can change anytime, with pow rules take time to change and that is not easily changed. So if you understand about mining, you will be a good trader because you know the depths of it, its limitation and from where it can go. To me all coins that can't be mined are scams, personal opinion of course.
