I don't accept it simply because it's not a stable currency

I signed up for a service that instantly exchanges the bitcoin for cash. The only problem is that I was not approved because you need a store front. grrrrrr

And what ever your opinion is on it I think it is gaining momentum and growing very quickly. It is also becoming more stable as large companies start using it.

In terms of mining it.. That has changed and only a small amount of people can now do it and have it be profitable. It takes a very, very powerful machine and lots of power to actually generate anything which is why so few are doing it these days.
This adds to the stability in a way.

Like it or not I believe it is here to stay. I would not mine iot or hold on to it but I would accept it from a few clients that I trust. I do know people that bought some years ago and they now have some decent profit from it but ofcourse these types of things are a risk.

So, back to my question.. does anyone here accept it and can you recommended a trustworthy merchant?

You do realize that virutally no currencies are actually backed by tangible assets, including the US, and most countries haven't been since the great depression.
