You know, the old "it'll be worth millions, or it'll go to zero."

Yeah, I don't think that. It could very well stay at $200 forever. It could be worth millions (very unlikely) or it could be worth ~$0 (unlikely, but more likely than the other option).

Okay, so what exactly are your reasons why it could go to zero?

1. Everyday people call it a ponzi scheme (regardless of the validity of the claim)
2. Someone in the bitcoin space is either shown to be insolvent, is hacked, etc, etc every few days.
3. People are mostly fine with what works now.

Those are a few reasons, and if I gave it more than 30 seconds of thought, I can probably think of more.

"It's never been done before" isn't a reason.

I would agree with that. There are plenty of problems with using that as a reason, but you're trying to preach to the choir of people that are mostly pro-Bitcoin (obviously, this is the Bitcoin subreddit after all).

If you're going to appeal to the status quo, then you should assume it will continue to gain traction, not lose traction.

I'm confused by this logic. Right now, I don't believe Bitcoin has succeeded yet. I think it's in this phase where we are still needing to see if it'll succeed (obviously the definition of success is subjective, but you get my point).

Also, you can still fail after you succeed.

Seriously guys, why talk about Bitcoin's potential for failure if you can't back up those statements with rational arguments?

You might get more (probably the same as this one and the other ones) or better responses if you post this on an "anti-Bitcoin" forum such as /r/Buttcoin or the likes.

But in all reality, there are a lot of rational arguments against Bitcoin (just like there are rational arguments for it, of course). Just because you may not like them doesn't mean they don't exist.

(Side note: If I come off antagonistic at all, I'm not trying to be; I'm just tired at the moment.)
