Bitcoin Forum

HI all,

Im happy to (pre) announce that in about 2 months I intend to start selling 100mBTC physical bitcoins. Im about to place the orders for the minting and the hologram design will be finalized in the next weeks.  Im posting this here to make you aware and gather some feedback before I pull the trigger.

These coins will be made in beautiful  bi-metal, just like 1 and 2 euro coins and be a bit thicker and heavier than Casascius coins. This is the almost final design of the front:

https://i.imgur.com/rvrrtvP.png

Feedback is welcome, but its unlikely I will change a lot.

The back will use the same principle as Casascius, with a fully custom tamper proof holographic adhesive covering the private key, while a window on the hologram will reveal the public key, possibly as QR code.

The reason I decided to go ahead with this is not so much to give casascius competition (I have the greatest respect for him and I am the proud owner of a fair number of his coins), its just that I used to hand out 1BTC coins as freebees, but at the current price, even Casascius new 500mBTC coins are rather expensive conversation starters.

Initially I planned to make these coins as cheaply as possible; using cheap aluminum and stock hologram seals with only a lasered public key on the holograph, but it would make counterfitting just too easy. Since most of the costs are NRE and the per coin price is rather low, I figured it should be possible to sell enough to enable beautiful and secure (*) coins that are still affordable enough to hand out. The NRE to mint the coins and produce the hologram is quite substantial, so I have yet to decide on pricing, but Im aiming for as close to face value as possible, particularly for large orders I hope to get the price (excl bitcoin value) in the single digit euro range. This wont make me rich, but for now Ill be happy to just recover the investment.

(*) About security; Ive looked at this from all angles, Ive considered doing 2 factor, but in the end Ive come to the same conclusion as Mike: its just not feasible for small denominations. So buyers will have to trust me that I dont keep copies of the private key and I wont steal their coins. Im banking on the reputation I hope to have among many here that used to trust me with their hashrate, and hoping the smaller denomination and small markup price - making it more likely they will actually be redeemed-,  will make that pill easier to swallow.

I intend to sell these coins directly for BTC but also for a higher premium through ebay and bitmit. On ebay these coins will also be sold for paypal; but will ship without BTC value until the buyer confirms reception. I hope that will provide me with sufficient protection against charge backs. Any knowledgeable feedback on this would be appreciated.

One thing I havent decided upon is a name. I still have a company that my brother and I registered a few decades ago  which was called Foresee. We will likely put this bitcoin business under that legal umbrella, so using that name is one option. But if you have any better suggestions, please PM me your suggestion. If I decide to use your name, I will gladly send you 5 free 100mBTC coins as thank you. Submissions should be sent within a week from now.

I will probably do formal preorders later, once I have a firm shipping date,  but to get a feel for the volume and amount of (dis)trust I have among forum members here, I would also appreciate if you posted a non binding "preorder" below indicating how many coins, if any, you would be willing to buy. Doing so will entitle you to a small discount once these coins  go for sale provided you actually do place the order.

Cheers,

P4

This is a great idea, and I'd buy 10 or so. It would also be nice to eventually see other denominations such as 50, 200 and 500 mBTC.

One downside of the holograms on casascius coins is that they're much less tolerant of the general handling and abuse that comes from being carried around in pockets and stuff, but I suppose there's not really much that can be done about that. Maybe have the hologram sticker recessed into the coin by a small amount (the thickness of the sticker) if it's not impractical.

Would faint latitude/longitude lines on the world map look good? What's the deal with the people around the edge? What will the other side look like? Reeded edge or plain?

edit: nvm, brainfart

I may do other denominations later. The most expensive is the hologram, single metal coins are actually quite cheap. But lets see if I can break even with these coins first before I sink even more money in it.


Casascius coins already do that, and so will I. TBH, those holograms seem fairly sturdy to me, I have yet to damage one by accident. I dont have a final design for it yet though, since I dont even have a name :). But it will look good :). Lead time for the coins is a lot longer than the holograms, so I still have some time.


Backside will have an edge so the hologram sinks in a bit.
The symbolism of the people seemed rather obvious to me? Around the globe people exchange bitcoins directly, p2p. THey are connected by small dotted lines. I think thats busy enough without lat/lon lines.

The symbolism of the lines and the people wasn't immediately apparent to me, but I guess it works.

As for a name, why not just P4coins?

Very nice design, I've always liked bi-metal coins. I would also like to put a pre-order on 5 coins, and maybe a few "broken" coins. 8)

Name suggestions:

Sector Coin
Chunk Coin
Bitecoin
Bytecoin
BitPart
Bit Segment
Bitstake
Quantumbit
Slice

Good luck with your project, I look forward to the final product!

I actually posted elsewhere that no one would challenge the Casascius brand, anytime soon. Looks like i may have to retract that at some stage!

I like 'Physcoin', and 'Bloccoin'

I would order 10.

"Phycoin" rolls off the tongue better than "Physcoin". That just sounds like fizz coin.

Just a thought. I understand why you would want to do this but you may want to consider the implications of your coins being "in the wild" with no assigned value. How can anyone trust your coin if there's a possibility it is not worth anything? I know it would be possible to check the public key but that's probably not a good expectation. You might just be best off assuming that you're going to lose some here and there.

And the more i say it out loud, the more i like it.....
 
"Ere Dave, you gotta couple of Phys, mate?" or "Thank you sir, thats 2 Physcoin change. Have a nice day".


Edit: How about 'Crypts' ?

Im not sure I see it as challenging casascius. Im aiming for the small denominations which he seems to be avoiding. If casascus was still selling <20 euro/dollar coins I wouldnt have started this, and just ordered them from him. Similarly I have no plans to produce any of the big denomination gold/silver coins and bars that he sells. I just want something again that looks neat, yet is cheap enough so people can give it away without thinking too hard about it.

Name suggestion: Decypher or Decipher. From Deci for 1/10th and cypher for the crypto aspect.

And don't worry about Casascius. Competition is good. He'll be fine.

As you mention; you can check the value easily using the pub key. I also dont see why someone would pay full price and not claim his bitcoins. The only reason I can think off is fraud, like claiming the coins were lost in the mail, but if I send by registered mail thats going to be pointless. If I simply never receive any reply, I might also just charge the coin after the paypal charge back period has expired.

Lastly, if for some reason other than fraud someone would end up owning a genuine coin thats unopened but without bitcoin value, or one that is open but on which address there never has been stored any bitcoins, it stands to reason I will back its value.

Whats wrong with fizz coin? I actually like that.

Depends what the perception would be when you look at the coin, between 'Phys' or 'Fizz', i guess.

If I can easily check the value of the public key, I can probably also easily use my wallet to pay. The scam I'm thinking of is this: Someone orders your coins, reverses the paypal then spends the empty coins as if they were fully charged. Unless someone checks the public key on the spot, they likely end up with an empty coin, potentially damaging your brand.

As to you standing behind the coin, I don't have much issue with you having had access to the private key but even with the best of intentions, I'm not sure how I'd feel about you standing behind them. Shit happens.

The simplest way to state the issue is that if I am handed a coin and the hologram is intact, I should feel 100% confident that I am holding a wallet that contains 0.1 bitcoin. If I have to worry about checking public keys or paypal abuse or whether you are still in business/alive, the value and point of the coins is diminished IMO.

Thinking about it, I think this may be a point Casascius hisself made to me when I made a similar suggestion to what your plan is.

I cant think of too many scenarios right now where that wouldnt be the case. Lets be honest, these coins are rarely if ever used to buy something (offline). They are used to store bitcoins offline, as presents, as collectible, or as a way to obtain bitcoins using paypal, but not as currency.


Yeah I can see that, but the trust issue already exists anyway, after all, the buyer has to trust me. So who is going to buy second hand coins and not quickly check the pub key? If its an online sale, thats typically already done for casascius coins too. Just demand a picture with the key and check its value, and/or use escrow (you might as well receive an open coin too). If its an offline sale, well, you would know that person.

Moreover, Im not sure how easy it would be to do a charge back if I send the coins with registered mail. And if I got my money, there is no reason I wouldnt back the coin regardless of who owns it.


I dont think that outweighs the downsides of sending only preloaded coins, and therefore being practically unable to sell them for paypal. As a buyer you already have to worry about me anyway. If you dont want to worry about anything or anyone else; either buy them from me, or check the pub key.

Anyway, I may change my mind on this if this is a wider concern, its just that I expect ebay to be a pretty big market for this and given the relatively small denomination, its not going to be a very profitable scam. Ill think twice before accepting large orders for paypal.

Sure. It's just my opinion and I stand by it. But I'm just one person so it would be nice if others weighed in. And, in the end, it's your decision anyway.

FWIW, I haven't checked my Casascius coin other than that the hologram was intact. Perhaps that's just me being naive though.

I like the name hardcoin.

I like the name hardcoin too.

Also, theres really no need to take paypal. Most people who would want the physical coins would already have some crypto currency.

Alternately, if you wanted, you might be able to work with bitinstant, and receive cash transfers through moneygram for orders over a certain amount. Then you get the funds almost immediately, and they can't be reversed.

Hardcoin isnt bad. Duly noted.


Im not convinced of that. Most people posting here, yes, but I think there is a sizable market for ebayers who just want to buy with paypal without going through the hassle of setting up wallet or using exchanges. Its more or less what Im betting on anyway as I doubt I will get the necessary volume from this forum or bitmit alone.


Thats an idea.
But perhaps I have a better one; what if I were to make paypal purchased, not preloaded coins distinguishable from preloaded ones? I will check with my supplier regarding cost, but I know he is able to print (/laser) colored text on top of the hologram, which is typically used for serial numbers or to customize off the shelve designs. So I could add "preloaded, value guaranteed if unopened" on one batch and  "check public key before accepting" or something like that on another batch.  Would that work? If the cost is too steep I might just use lightly colored paper for the pub key to distinguish them, though obviously Id prefer it to be more clear.

Gonna list two other names I like, just so its on record:

Cytoc
Crytoc

(dropped some letters from cryptographic currency)

And one more:

Bling

Perhaps a way to work it would be to sell the coins but have the buyer load the bitcoins.

Not sure how that would work though. Maybe you would have to keep hold of the coins until the buyer loaded them. But then if the buyer refused to load them, there would be some dispute. Then the buyer might initiate a reversal with Paypal. That would leave you with the coins but if that happens a few times, Paypal might decide to cut you off.

Edit: Plus this means the buyer needs bitcoins in the first place, negating a lot of the advantage of what you're trying to do. Nevermind.

I am totally cool with this, I encourage competition, and hope this works out well.  I will also be happy to order some.  I honestly wished this happened a long time ago.  While flattered to be the only person producing physical bitcoins, it's not the way I think things "should" be.  Someone who can do a better job of this, should do a better job of it.

Keep in mind that my ulterior motive in producing them in the first place was to promote Bitcoin.  Their creation was motivated by my awareness that people need something physical to be able to talk about Bitcoin to those needing a shiny thing to hold, and that my creating them was going to have a direct impact on the number of Bitcoin conversations happening around the world.  That need hasn't changed, and making a pretty 100mBTC coin given today's rates is a clear example of being attentive to the needs of the market and the potential user base of the coins.

Likewise, welcoming competition is consistent with my original stated goals.  The fact that I have earned a well seeded reputation that results in people being willing to pay the amounts they pay for my original coins is plenty rewarding for me.  I do not need to be the only one making these.

I have one bias I'd like everybody to be aware of, and this concerns both new creators of coins, as well as those who buy the coins.  I am biased in favor of people creating coins who have a good track record of being in business IRL and who maintain a net worth approaching or exceeding the value of the promises they might issue.  A promise not to steal your bitcoins is a promise that can be broken.

What you don't want is a situation where someone is tempted by the opportunity to run and disappear with other people's money.  Depending on which prevailing story you believe, people grossly underestimated this risk with Bitcoinica when deciding to send large amounts of money overseas to a 17-year-old for safekeeping.  The community needs to have learned its lesson by now.  A reasonable policy is to demand 2-factor on all physical coins above a value you could afford to lose if the person who made the item defaults on the trust you have placed in him.

The only challenge I have to those producing physical bitcoins like mine, is that I demand that they prove themselves capable of producing coins securely, properly, avoiding risks of hacking and key compromise, as well as proving themselves worthy of the community's trust.  Meanwhile, I insist that the community not lose sight of the importance of this.  I will really, really, really be bummed the day some future producer of physical bitcoins tarnishes the whole concept by ripping off his customers (or even the day people find unredeemable coins due to production errors), and so I favor accountability and I favor producers having a major sort of skin in the game.

To everyone buying physical bitcoins, please remember that you should always be able to name ONE individual who is responsible for the coins you buy, whose ass is willing to be kicked, and you should be able to assure yourself you'll be able to find him/her if you need to, and that person needs to be able to afford reasonable mistakes, as well as to be sued.  You do not want to hear "sorry I screwed up, but I'm broke, so your loss", nor do you want to hear your attorney say "I'm very sorry for your loss, but you can't get blood out of a stone".

That said... I hope this turns out well!  I would offer naming suggestions, but I think any suggestion I offered would be prejudiced just by me having offered it.  I might offer thumbs ups, thumbs downs, or my comments on other names I see though.  Casascius is a word I simply made up.  I have filed for trademark status on it (my attorney accepts bitcoin!)

I was going to say, one day they ought to erect a statue for you, but instead as a tribute, maybe I should mint coins with your face on them instead :).


Its another reason Im going for small denominations. Depending on final cost and pricing, if I were to steal all the unredeemed coins at some point in the future, I could probably not even double my revenue and its not exactly going to be enough to pay for a one way ticket to an exotic island. What I could potentially gain is a pretty low incentive, particularly compared to the 100BTC bars and the like that you are selling.
If you were to steal the bitcoins you have sold you could probably buy the island by now :).

.

I mostly agree.
Im not entirely sure yet if or how I will handle this as a legal business, but plenty of people here already know who I am and were to find me.  
As for my trustworthiness; that will be for customers to judge and weigh against the incentive I would have for ripping them off. I know you are speaking in general terms, but for the record, my first batch will be 1000 coins of 0.1 BTC. Assuming I actually manage to sell them all, subtract any redeemed coins and whats left is a very complicated, expensive and risky way to try to con people out of ~50 BTC. I can think of easier ways.


Feel free to offer. I can always say no :).

Crytec or Cryteq sounds cool!

I like Cryteq!  Way better then Cryhard =)  lol.  P4man you should make a pre-order list.  I'd love to order a few handfuls from you...just what I need to pass around to friends and family!  It's perfect

Crickets
Cryptics

Cryptoken! Cryptokens in plural :)
Great initiative, I would definitely be interested as casascius have become quite expensive..
Also, where are you situated? US or EU?

Name suggestions:

decimus
decima
decimum

They all are ways to say "tenth" in Latin, since these are a tenth of a bitcoin. I think decimus sounds best.

Belgium, EU.

I probably will, but certainly not before I ordered everything myself and have a firm shipping date. Otherwise Id have to call it "butterfly coin" ;).

Having people on the side is tasteless, you need to embed more of the very human nature that has led for us to create this very technology, probably write "Caput Mundi", "fiat lux" or "Sic semper tyrannis" on it.

Tasteless? What makes you say that? I think its subtle (keep in mind actual dimensions, you will barely be able to make them out) and looks rather good, while the symbolism of users exchanging coins directly and globally seems perfectly appropriate. Isnt that the essence of bitcoin?

As for the slogans. I can certainly appreciate "vires in numeris" (who came up with that actually?) but Im gonna stay well clear of any political slogans. Its a coin not a socio political pamphlet.

Someone needs to get some Satoshi coins made. It would be a bit of a laugh and handy when they become worth $10/piece.

My comment:  Why is the 1 larger than the two zeros in "100"?  Looked a bit odd to me.

I propose the name BitBobs, "bob" being the slang name for an English shilling which was equal to 12 pence.

That would be more appropriate for an 0.05 bitcoin piece though.

Nicely done. I like that.

Those were the days, eh?...."yer got a couple ov bob on yer, cock?" !

How about "mills" or "bitmills" It rhymes with "bill" like fiat bills but is also bills and mili(bitcoins) combined in one word.

Current short list:

Cryteq
Hardcoin
Bitbob (isnt that nickname of someone here?)

Cryteq sounds the best to me, but Im slightly worried Crytek may not like it. Bitbob is kinda funny, as my first name happens to be Bob :).

Keep 'm coming.

I'm against cryteq or variations on it. It sounds kinda dumb (faux-cool; you're naming a coin, not a gaming PC) and doesn't really tell you anything about the product. If it has to be one of those three, please use hardcoin or bitbob.

Bah! "Clever" names end up being silly.

I suggest using normal ordinary words. Consider gold and silver coins -- you have "maple leaf", "buffalo", "eagle", "panda", "lunar", "kangaroo", etc.

Since your coin has a map of the world on the obverse, use "world". Besides, it is just a trademark on a hologram. It doen't have to be the name of the coin.

On the other hand, if you want to give it a name, do what some software companies do:  name each denomination after a kind of tree, or mineral, or breed of dog (Apple already uses cats), or something.

I'd probably order between 10 and 50 if the premium to face is very low, and if I like the final designs and name. This also assumes that after I dig through your post history, etc, I don't uncover any trustworthiness red flags. I also echo Mike's concerns regarding private key safety. 100mBTC coins can add up, and it would be awful for bitcoin in general if a bunch of physical coins end up getting cleaned out down the road, be it from malice or negligence. Mike has earned the trust he has in the community by publishing his real-world details, crypto-signed communications, and producing a number of tools that indicate his technical ability and attention to detail and security.

You make two valid points.
Regarding the year, it would be cool to introduce a new year counting, instead of AD, we used AS "Anno Satoshi" :) but no one would understand it and a coin is not the place to invent, let alone explain a new dating system. Unixtime might be more neutral, but it would hardly look good ('1366873851") and having a precision down to a second makes no sense.  AFAIK, all other bitcoin tools, including the official client, blockchain.info etc all use the "christian" year, so Im not sure this is a big deal, but perhaps I should just drop it all together.

The point about the silhouettes is quite valid. Although I dont like the idea of naked people (that seems more appropriate when you refer to people in a medical/biological sense, rather than a business sense) and they shouldnt be too cartoonish either. Ill see what I can do to make them more generic though. Thanks for bringing it up.

Im painfully aware of those issues, and I do agree that a malicious (or incompetent) supplier of physical coins would be terrible for bitcoin. Its also a reason I want to do this; someone besides Mike is going to sell such products sooner or later and at least I trust myself more than I trust someone I dont know :). No matter what I do, I can not make you trust me, but thats ok. I prefer taking the risk of not selling enough coins to pay back my investment over seeing someone else pull another pirate like scam with physical coins.

I have ample respect for Mike and will gladly use his expertise and implement his good ideas, possibly even his tools, and draw from the community at large, but its not an insurmountable challenge to produce the keypairs on an offline airgapped machine and securely format and/or physically destroy the ssd or usb key afterwards, wipe printer memory if applicable etc. I will explain in detail how I go about doing this before I actually produce these coins, but I cant do that now as I am yet to decide whether I will print keys or buy a laser engraver, use QR codes or not. I will be experimenting first once I receive some blank samples. I also have yet to decide on the software, Ive looked at the tools Mike published, I will look in to Armory. Either way I will be completely transparent about how I make these things.

If we are honest, when applying sufficient paranoia,  common sense and proven software, the real issue isnt accidental leaking of private keys, its deliberate theft. Mike is currently trusted for over $8 million worth of bitcoins. Thats a huge amount of money to trust anyone with, and frankly more than I would even want to be trusted with.  Im not sure how to put this without being misunderstood, its not like I distrust Mike, but publishing personal info (which I will too) or crypto signing messages (?) isnt enough to warrant $8M worth of trust. We are all taking a leap of faith here, myself included as I do trust him, at least for the handful of coins of his that I own. By comparison, my first production run will amount to $15K worth of bitcoin at todays value, assuming I would sell out, which is far from certain. Thats not pocket change, but I think you will agree its quite a different level of incentive,  its almost 3 orders of magnitude lower.

Trust is built over time, and while its never absolute, I have to start somewhere.

What a bad assumption! Who coloured your picture of Africa?

The Vitruvian Man pictured on that coin is not just a naked man, and the context is certainly not business; as Im sure you are aware, its a famous drawing by Da Vinci about anatomy where nakedness obviously makes sense. LIke I said, biology. Other examples you may find will probably relate to the ancient Greeks or Romans, where the context is historic.

Its not that Im offended by nudity (although, some Muslims might be), its just that it doesnt fit here IMO.

Regarding the year, is there any milelage in counting backwards to when no more Bitcoins will be produced? So this year will be 2140-2013 = 127. Or you could express it as 'T-127' Next year T-126, and so on.

It would add a conversation piece, which has real value, as it happens to be a fundamental truth/fact.

We dont know exactly what year the last bitcoins will be mined. But perhaps we could use the % of coins minted to date.

Yes. I was thinking of some kind of symmetry with the number of blocks completed, also.

Without going off-topic, is it fact that successful mining COULD take place before 2140, and fundamentally CANNOT after this date? Is my understanding correct?

The date 2140 is a bad date to reference as it is actually just an emergent property of the number of decimal places in the current implementation (eight), and how long it will take for the reward to get so small as to not be representable without more precision.  If the precision is ever increased, the 2140 date will become irrelevant.  And that also assumes that the date won't drift with difficulty changes (it probably will - example, it already drifted more than a month for the first halving - Nov 2012 instead of Jan 2013).

No where near as fundamental, as i thought. Cheers Mike.

Be aware that casting metals is difficult work, and carving metals tends to be a bit expensive. Depending on the metal you use, and the size of the coin, the small detail of this coin could very well be lost. I'm wanting to make physical coins myself, and am getting an education by someone who does them for a living. Just be aware that the metal itself doesn't necessarily hold its shape if used, and so the smaller details can wear off or wear down if, say, someone carries this coin in their pocket.

Love the basic idea, otherwise.

As to the name of your coin, I'm unclear... is this a name for the entire line, or is it for this particular denomination of coin?

They are neither cast nor carved. They are stamped, just like our regular coins. That enables fine detail and yet they are quite resistant. Maybe not quite as sturdy as fiat coins, I believe the metal alloy is slightly softer as the pressure at which they are stamped is probably not as high as the huge machines our mints have, but the samples I have are quite tough, not sure if its any worse than normal coins,  and much more resilient than the hologram anyway, thats always going to be the weak point for someone carrying coins in his pocket.

To give you an idea, this is a scan of an older, abused 25mm sample coin:

http://i.imagebanana.com/img/bpbcztkx/munt2.png


Its a common name for the entire line, assuming there will be one over time. We cant just call it "a 0.1 bitcoin coin",  people need a way to differentiate between coins from various suppliers.

I have faith that they will release the butterflies soon... right after they have built the pot for the leprechauns to fill inside their own house at butterfly-labs. 10 for them, one for us... they win! Welcome for the investment, thanks for giving us the scraps! lol.

I like the bitbob suggestion, as it ties in with 'mainstream' tokens. In a similar vein, how about...

- Benny (bit+penny)
- Bounder (bit+pound...er)
- Billies (bit+millis)
- Betas
- oh God these are actually a bit dire. Or druggy.

OK, take 2...

- Blockcoins
- Keycoins

Got to keep it simple...

Bitbobs is my fav, I liked sacko's design too :P

How about doing your dashed/dotted lines in the shape of a 7 pointed star, like

Crypts or cryptcoin.

Cryptcoin seems to stutter in the mouth, so Crypts for me.

To me, "Crypts" sounds like "crips", which sounds like someone with a speech impediment asking for "crisps".

To me Crypts links more to an underground burial place like under a church (http://dictionary.reference.com/browse/crypt) than to Crypto coins, also it sounds too like the gang name Crips (http://en.wikipedia.org/wiki/Crips) for my liking.

Not to forget that we are currently living in the year 102 of the Republic of China (http://en.wikipedia.org/wiki/Minguo_calendar)... with "Republic of China" referring to the tiny yet democratic island of Taiwan by the way, not to be mixed up with the giant communist thingy called by almost the same name, only with an added "People's". Which uses 2013. And by a freak chance it is also the year 102 in North Korea (http://en.wikipedia.org/wiki/North_Korean_calendar), simply by the coincidence of  Kim Il Sung's birth having been in 1912, where in China the new era of the republic had started (and lasted till 1949,when the communists had won the civil war aka the next revolution). Oh, and the Japanese Taisho period (http://en.wikipedia.org/wiki/Taish%C5%8D_period) also had the same numbering of years.

Which leads me to my point, finally: since the creator(s) of Bitcoin chose a Japanese pseudonym, numbering years in Japanese ways might be a way to honor this aspect of Bitcoin's "birth". Similar to the Chinese, to my understanding Japanese traditionally counted years from the start of a new era (http://en.wikipedia.org/wiki/Japanese_era_name). This era in our case could be the start of the Bitcoin network in 2009. Of course this obvious counting method has already been suggested. I am simply trying to point out one possible reason supporting this kind of counting.

To identify the era name, obvious choices would be Satoshi, Nakamoto or Bitcoin. So the current year could be called S5, N5 or B5.

A reason for not using S5 could be that it could refer to year 5 of the Showa period (1930). In this period the then militaristic Japan caused huge grief and suffering throughout Asia.

A reason for not using S5 or N5 would be that Japanese era names are not referring to the names of the respective emperors or events, but to a description of that era.

So B5 would be one possible choice in my opinion. Or if you want to go all Japanese style, ビットコイン5... or even replace the "5" by Japanese/Chinese numerals, resulting in ビットコイン五 - although probably most Westerners without Chinese/Japanese reading skills could not identify the numeral, except probably those few who play Mahjong and recognize the numbers from the WAN tiles (http://en.wikipedia.org/wiki/Mahjong_tiles) :P

I would avoid any name that contains word coin. With new altcoins being announced on daily basis you'll have problem to make a brand from your business.

Find your own fancy and exotic version of Casascius. Make it to sound non-english - spanish, portuguese, arabic.. something like that, japanese is not bad too but I would avoid it to not cause confusion with satoshi.

Brand is half of business, if you name it Hardcoin, I'll forget what it is in month and when I hear it next time I'd automatically think it's some of million altcoins. When you name it Bitinho or something like that, I won't.

Or Cryptie  ;)
CryptieCoin

I want to thank you all for your suggestions, ideas and support.
The name has been decided on last week, but I want to keep it a surprise.
I will say if it were a guessing competition, seleme would have won :).

I'll suggest something like a combination of previous ones suggested for this coin:

Cryptiq decimus

or perhaps the better spelled

Cryptic decimus

I like the whole combination for the line but if you just wanted to call the line Cryptic with decimus reserved for the 0.1 BTC coin and other words for other values (Cryptic mill = 0.001, Cryptic centavo = 0.01, etc.)

Another idea would be

Mundo (Spanish for world, similar word to Euro but more all encompassing)

What happened to this? Is this dead?

OP can't put in the effort to spell and use punctuation, I wonder if he is a minor.
