The comment you replied to is the source. What other type of source would you like for what something "seems" like to an individual?

It seems to me that asking for sources is a common technique for discrediting opinions on HN. It looks like a legitimate question but obviously if they had a source it would be a fact rather than an opinion.

If you are actually interested in how that opinion is formed ask a relevant question or point out what they are missing.

Personally I find that opinion entirely reasonable given that there are no problems I have that Bitcoin would solve better than the alternatives unless I was inclined to buy something online anonymously or to speculate on Bitcoin itself.
