Hi. Serious question. I'm new to this forums and new to a few coins I'm looking into, but not new to bitcoin. Any time I make posts or comments, someone always has something really pessimistic or rude or judgmental to say. Just doesn't seem friendly to new people or those who think outside the box. How come?

I'm doing some research and would love everyone's insight.

What makes crypto-coins fail, die, go out of business?

I'm looking for specific things that are tied to a coin failing. I heard many coins fail because they're dumped and so value leaves the economy. What else makes them fail?

Hi there, I'm new to the forum. I was thinking of creating a coin for my town and promote it to the town and local businesses. Has this ever been done before and what do you think some of the considerations would have to be in developing such a coin? The point would be to have a coin for real local trade from yard sales to supporting local business (non-national franchises). And exchanges would be mostly done using mobile wallets and technology. So you could go to a yard sale and a customer could use their phone to scan a label on an item or the salespersons phone, or they could scan the customer's; and that's how transactions happen. It could be promoted in local papers and local media TV/Radio/Net/Ads + Flyers and things. No rush-- just wondering if it's been done and possibly what kind of challenges would be faced? What considerations would have to be made?
