I think yes , here it doesn't matter that what we are thinking but we should see real factors also that we are seeing .
A magazine that I seen once about 2-3 months back about the bitcoin that how it is effecting our life in positive and negative way .
There was something like to produce heat by the miners and use of electricity for the miners that are effecting the environment much .
But here we should not see towards such things which are not in actual are part of our Life to make effect badly because many other things are also effecting this world which are not taken in consideration by the writer .
Here we are happy with the bitcoin use and I think its negative impact is about negligible then what we have positive and better impact in our economical life .
