The difference is the dot-com stocks had some theoretical value - even Pets.com, people buy pet supplies online after all.<p>Unlike commodities, equities and so forth, cryptocoins have no value whatsoever. So to try to make it sound like it has worth, its pushers have to cast about for anything they can and finally come upon the only thing they can - the dollar. In fact, they say, it's even better than the dollar.<p>It would take too long to explain here why the Bitcoin is not like the only thing they have left to compare it to, the dollar. Also, an explanation won't sway anyone who has already had a drink of the kool-aid any how.<p>May I recommend another message board for all those high on cryptocoins here - 4chan ( <a href="http://boards.4chan.org/biz/catalog" rel="nofollow">http://boards.4chan.org/biz/catalog</a> ). 4chan /biz/ is filled with uneducated, poor kids all looking to get wealthy with little work on the cryptocoin get rich quick schemes.<p>I think it's a much better message board for all of you of this bent. Here on HN there are still some people who believe in studying math and science and engineering and CS at universities, and then going and doing a lot of hard work and creating wealth. 4chan is mostly filled with your types - the get-rich-quick scam artists. Go read 4chan /biz/ right now - it's filled with no work, no study, get rich quick types like yourself. Leave and go there. HN will be stuck with those "out of it" old fogies who actually believe in study, hard work, that commodities need value to have worth in the long-term, and old-fashioned, out of touch ideas like that.
