When re-reading the OP's comment just now, I just can't interpret it any other way other than "see! crypto bad". Maybe I'm missing something.
I'd accept that my responding, effectively in-kind ("see! your position bad"), isn't particularly useful other than potentially alerting them to the fact (my intention), and I'd no doubt do better to provide some examples of benefits at least (as I see the current top-voted reply did, that is otherwise identical to mine).
My admission of that however, does not indemnify the original commenter - at least, in terms of my interpretation of their comment, which is really all I can be responsible for.
