Somebody should start a bitbet or arrange an escrowed bet.  I'm guessing this will be gone in 2-8 months. It's hard to predict the demise of a ponzi, but the greater the rate of the return - the shorter it lasts.

2 seems harsh, they would have stopped deposits already since minimum contract duration is 120 days.

Ah, I wasn't aware of that. I was looking at the pages that talk about each share type. You're right! So that makes it basically 365% APR at today's rate.

365% APR is too much, remember they do not trade in weekends and UK holidays. I have made a projection on a Excel file where I compound interest for the first 120 days and then cashout earnings for 120 more until the last share expires.

Result: 297%. Performance varies based on investment (should I say "bet"? Smiley) size since you can only compound 20$ "slices".

understand but i will not accept escrow
its a risk for sale i know  i accept that
i can provide many things better than escrow

That's sad as we are near, I am from Italy.
Good luck with your sale

Escrow is not bulletproof, read the thread where he got scammed:  https://bitcointalk.org/index.php?topic=508790.0

That is sad indeed.
But I'll buy only with an escrow I trust  Smiley

You clearly have no idea how real arbitrage trading works and you're not going to listen to anyone who might burst your bubble, so why bother.

You shouldn't. "Dismiss by ignorance" is a way of life I do not like, but I'm not judging you.

I've made my due diligence before investing a small amount in this program and my oldest share will expire in two months. We will see who is right  Wink

not accept escrow i have bad expericence with that

You have no trust from reputable members, if you do not accept escrow trading is impossible.

Please tell us which escrow caused you issues so we can avoid him  Roll Eyes

Of course X matters. The profit (before transaction costs) will be X*(Z-Y), which makes the size of X just as important as the size of the spread. If X is just $1/day there's not really much point.

No it doesn't since X is not $1 but a lot more, volume is in the hundred of BTC daily.

The fact that Bitcoin-trader claims to have about the same profit level now as in the beginning is just more evidence that they are lying and that it's a ponzi. Another evidence is their claim of not trading on weekends. Anyone doing real Bitcoin arbitrage knows that you need to automate it, and when that's done there's no reason for not running it 24/7.

I can't say anything for sure, but these reasons you provided are pretty silly. Automatic trade within an exchange is easy to do, automatic arbitrage between exchanges is extremely difficult to implement, fund and mantain. They have software to aid them for sure but 100% auto? Crazy.
Just to mention something: the weekend would be a good time to "clear house": rebalance accounts between exchanges and cash out earnings.

So far they look legit and are paying, is this enough? Dunno, I'm pretty sure the scam induced paranoia has smothered many good ideas.

528  Economy / Service Discussion / Re: bitcoin-trader.biz on: May 18, 2014, 06:51:33 PM
Hmm, so I guess I should be using the term liquidity instead of slippage?
Eg. I get a market signal to buy - but there is only 0.01 BTC available at the current ask, so if I want to buy at higher asks.
This makes it a lot easier to do arbitrage with small amounts than with larger ones.

The only thing that an arbitrage trader should really consider is: average spread.

As long as you can buy X BTC at an average price Y at exchange 1 while you sell X btc at an average price Z>Y at exchange 2 you should do it. X's size doesn't matter.

It gets a bit more complex when dealing with multiple exchanges simultaneously but the concept is the same. Average buy vs Average sell Wink

So the answer to your question is yes: I could buy at higher ask IF I want, this will raise my average buy price according to the volume purchased. But it can be profitable anyway if the other exchanges have enough volume and profitable sell orders.

if it is 1.25 LiteCoins.... looks expensive  Grin

.17

The high bid so far is 0.17BTC. Let me add that escrow is always accepted. I do ask that the winning bidder cover any fees or donations for escrow. Less than 12 hours to go; let's see some more bids.

Hi, would you please provide a quote for shipping the item without PSU to Italy? I would bid but I am afraid of shipment.  Smiley

Can you show us some photographic evidence to prove that the product exists, along with some hashpower proof?
It would be awesome if you shipped one to a trusted forum member, so they can verify its existence.

A skype call is more than enough. He could talk on skype while the miner mines on an account of the trusted forum member at the indicated hashrate for an hour or so. Hard to SCAM anyone this way.

Complimenti ottimo lavoro!

Slippage is the difference between what you can buy 0.000001 BTC (or an infinitely small number of BTC, or the smallest an exchange will let you trade) and what you will pay to buy N BTC.  The greater N, the greater slippage.

Another way of putting it - there are more arbitrage opportunities for trades of 0.01 BTC then there are for 10 BTC.

I beg your pardon but slippage is "the difference between when the computer signaled the entry and exit for a trade and when actual clients, with actual money, entered and exited the market using the computer’s signals. Market-impacted, liquidity, and frictional costs may also contribute."

So if you try to do arbitrage moving BitCoin between buy and sell actions you will suffer slippage as you are unable to do anything during money transfers when price moves.

Viceversa if you are "solid" enough to keep liquidity in multiple currencies in all exchanges (as real big banks/traders do) you won't suffer slippage. You may have few occasions as cryptocurrencies market is low compared to bigger ones like forex but that's it.

Yes I am sure.
That is a separate adventure of mine. I do not like to keep all of my eggs in one basket especially in BitCoin matters.

Bitcoin Trader deals with Bitcoin Arbitrage, mine is an AltCoin trading bot.

A me sarebbe interessato acquistare qualche share, ma non mi tornano i calcoli ...

Come ho scritto più volte sono delle stime conservative, non ho considerato il merge, non ho considerato l'aumento del valore del BTC che adesso è sui minimi... ho considerato valore 0 di vendita dell'apparato.
Ci sono tanti ragionamenti profittevoli lasciati fuori proprio per attirare le persone, era una ottima opportunità specialmente dopo stamani che avevo ricevuto una offerta per 7 centesimi di euro al kWh che stavo perfezionando.

Quel che mi deprime di queste opportunità è che scivolano tra le dita mentre gruppi che imbastiscono acquisti in preorder di un miner scrypt a prezzi osceni di cui si sa FORSE l'hashing, FORSE la potenza e FORSE la data di consegna vengono riempiti in pochi giorni.

Ma tant'è, inutile recriminare. Grazie a tutti per i commenti.

Up! Come on people, I've already got trust from Lucky Cris but I would like a lot more  Smiley
537  Local / Hardware/Mining (Italiano) / Re: [GROUP BUY] Cointerra Terraminer VI - ~5 BTC on: May 17, 2014, 05:09:23 PM
Il merged mining lo fanno pool come GHash.io; in parole povere ti fanno minare altri coin insieme ai BTC a costo zero per te.

Temo comunque che il problema non si ponga più: il venditore mi ha appena comunicato di aver pronto un acquirente USA per 5 BTC. Darebbe la priorità a me ma noi qui siamo ancora in alto mare.

Peccato.
538  Local / Hardware/Mining (Italiano) / Re: [GROUP BUY] Cointerra Terraminer VI - ~5 BTC on: May 17, 2014, 11:54:12 AM
Imho ti conviene rifare i calcoli sulla base di questa tua nuova scoperta, dato che i neptune sulla carta dovrebbero arrivare molto prima rispetto a quanto avevi preventivato

I calcoli li ho fatti su http://cex.io/calc da adesso in poi con i seguenti parametri:

Hash Rate: 1600
Maintenance/pool: 0%
Difficulty: 8853.42
Difficulty Increase/Month: 50%

Chiunque può riprodurli e come vedi per la fine di luglio sarebbero 5.78 BTC. Visto che siamo a metà maggio ho fatto una assunzione conservativa dicendo che il ROI è a fine luglio quando probabilmente sarà metà luglio.
539  Local / Hardware/Mining (Italiano) / Re: [GROUP BUY] Cointerra Terraminer VI - ~5 BTC on: May 17, 2014, 11:45:02 AM
Ah che il q2 è aprile/maggio/giugno

I quarti sono quattro non 2  Wink

Ottimo, a quanto pare qualcosa mi è sufggito.
Che dire, vediamo se onorano entro la fine di giugno  Smiley

Non penso KnC andrà addirittura a consegnare a settembre-ottobre, mi sembra più realistico pensare che tra un mese i vari Neptune saranno già attivi e si ritornerà ai vecchi 20 e passa% di salita ogni 12 giorni

Loro dichiarano che mirano al Q2 del 2014 ossia luglio/agosto/settembre. Secondo la mia proiezione il Terraminer IV fa ROI a fine luglio.

Direi di aver pensato a quasi tutto, mancano solo gli investitori e un paio di risposte sull'hosting  Smiley
