Coin itself is just a nice thing to show off to your friends. :) Is it paradoxal? Yes it is. Just like a use of coin in the name Bitcoin and it's actually a line of code or a line of characters which constitute your private key, not a coin at all.

There are some variations of this method. Some like silver wallets you put your own in. You get instructions on how to make it and put it in coin, then cover with special sticker. Others are pre-done. Some come loaded (or filled with BTC), others have no btc in them. It varies greatly depending which coin you are talking about. But in general they all work the same way in cold storage with paper wallets. Title: Re: How does the physical coins are made ?

I bet that things won't be so cheap and it's really worth since the coin design with care , have a hologram so it's quite beautiful Title: Re: How does the physical coins are made ?

You have to trust the person that makes the coin. That is why DIY coins have little resale value. Title: Re: How does the physical coins are made ?

You have to trust the person that makes the coin. That is why DIY coins have little resale value. Unless they are not put together. I have a silver wallet never used as I wanted to keep it new. I think a lot of DIY are not used and put in safe keeping. But I will admit even on well known ones I have always been afraid of having to trust a 3rd party who puts coins together. I don't think we have seen any problems on it, just scares me personally. Title: Re: How does the physical coins are made ?

I think there are nothing can stop, except you make your physical coins for yourself. I think the creator of physical coins is need to prove their real-world identity.

Trust would be a problem when bitcoin is worth multiple-orders higher than the price today. Coin makers will not use all of the coined keys, that would be too obvious. Just take any 1 key and no one would suspect. :-X Title: Re: How does the physical coins are made ?

I like the coins that allow you to do the paper yourself. It just makes me feel more secure. And I know some of the big coins are considered very trusted, I just am extra cautious.

For gifts, I just print paper wallets with a cools designs. :D Title: Re: How does the physical coins are made ?

There is someone right now who has the Casascius bar with 500 btc on it. And it's hard to tell it's actual worth. It is crazy think of it's value to physical coin collectors. |
