Indonesia, especially Jakarta is in a pollution emergency, Many say that this is caused by steam power plants where the fuel is coal. And, sadly I heard also on my social media local that this pollution is also caused by crypto-mining, I debated and rejected it opinion because crypto-mining in Indonesia is not much like other countries where their air is still clean today.
So what do you though, is crypto mining become a big problem of pollution?
Well, I think you already answered your own question, since 2016 I joined crypto, this is probably the first time I am reading about cryptocurrency(Bitcoin specifically) mining and Jakarta, Indonesia together, both on this forum and outside the forum.
I personally think Indonesia is not such a big market when it comes to crypto mining, they do not have as much candidates in this field to warrant them going through a pollution crises .,
So I personally think that the cause of this might be what you suggested at first which is steam power plant where the coals are tuned to fuel.
