Coming from a newbie. Yeah, likely a stolen account.

And HideMyAss service is shit.

I came here to explain exactly that. I don't have a debit card but saw the hidden fees. At this exact moment, rates are:

Bitstamp BTC price is @ BID 331.65 - ASK 331.95
ANXBTC  BTC price is @ SELL (how much they pay for your BTC) 324.00 - BUY (how much YOU pay to buy BTC from them) 354.88


The only service they offer that I would consider is the debit card. You put BTC for free, convert to USD @ 3% exchange rate fee and spend online. Useful when you cannot buy stuff cheaper directly with bitcoins.

The concept of a crypto-currency investment is marvelous. You don't need to fill paperwork, show id… You just transfer X amount and you are already a stock owner. A company located anywhere can get funds from anywhere and pay dividends without fees nor getting robbed paying taxes.

Hopefully in the future we can all invest in companies this way. Companies couldn't cook the books since we all could see transactions/sales.


Like any stock in a common stock market, we should see if the company is a good investment. Just because I like a Big Mac, I won't invest in McDonalds.

PETAMINE has a lot of hash power, has a cheaper GH/s per dollar comparing to CEX.IO, reinvest part of the income to increase it hash power (and increase the chance of having an income)… It looks great BUT:

Operating expenses seems too high in IMHO. A mining farm should be where electricity cost is near-zero and having less employees as possible. I would like to see the financials; How much goes to employees, how much goes for electricity… Otherwise I don't know if it is a good investment.

Se vocês estão começando, recomendo no mínimo baixar as taxas pra que haja volume e alguém queira comprar/vender no BaseBit. Que tal usar as mesmas taxas do BitInvest? 1% pra saque ou depósito em R$ e 0.3% pra ordem de compra/venda?

Execução de ordem passiva? Me perdoem mas acho isso ridículo. Vocês tem que cobrar pela ordem executada apenas.

O problema das bolsas no Brasil é que todas tem um volume muito baixo de negociações. Outro problema são as taxas.

Mercadobitcoin.com.br
Acho que é o mais antigo e nunca tive problemas quando usei umas poucas vezes. Tem posts aqui no fórum dizendo que esse exchange já roubou bitcoins ao fingir ser hackeado.
Taxas meio abusivas. 2% pra retirada + 2,90 reais. Sem contar que tem mais 1% pra executar ordem.

BitInvest.com.br
Nunca usei mas tem um site bonitinho, sabemos quem é o dono.
Taxas são baixas 1% pra retirada em reais e 0.3% pra ordem de compra ou venda.
O que não gostei nada é que no site diz VOLUME de +50 BTC mas quando olho as negociações, não é nem 1% disso. Ou aquilo é Volume ANUAL ou mentira (como já aconteceu com um exchange na China).

Basebit.com.br
Volume é ainda mais baixo que os outros.


Deles acho que o Bitinvest promete mais, porém nunca o usei.

Bitcoin unfortunately It is not the best means of exchange. I still find it easier to pay something using a credit card. You just swipe your credit/debit card into a machine and type a few digits (password). Bitcoin should be easier than that to be more widespread. Not everybody is tech-savvy.

What about creating a hardware wallet as small (preferably smaller than) a credit card without the need for a smartphone or computer? How difficult could it be?

To receive money you just need a QR code (could be printed on a card like versocards.com).
Unfortunately for PAYING is not the same. You can't go around putting your wallet private keys on other people's QR code scanners.

Is there any solution I'm not aware of?

I know someone who works in advertising that could be interested. I imagine you use bots but how do I know Facebook, Twitter, etc won't delete those fake likes/followers?

Actually I didn't bought the miner. I WAS about to buy 3 units (4500 gh/s). Did my diligence and realized it was too good to be true (ROI in 2 months). Maybe I'll buy an SP30 (1 dollar per Gh/s) if the price stabilizes and they ship (no pre-order). We don't know what will happen in 3 months.

Crominer,

Unfortunately most profitability calculators don't take into account difficulty increase. I went to coinwarz.com and saw I could make 0.0481 bitcoins a day using a 1000gh/s machine. I multiplied for 365 and thought I could make 17.55 bitcoins in a year! That would be almost 8.000 usd if the price kept at 450 usd/BTC.

I thought, WOW! I could buy an Antminer S2 for 2k usd and break-even in less than two months! Too good to be true. I checked other profitability calculators and all gave me the same number.

Then I checked tradeblock.com/mining/
So even with free electricity, a mining rig ROI+20% would take a year with FREE electricity!

And hardware companies are lowering the price constantly, it's more like gambling. You're not going to recover your money (and time). And when you buy a 1000GH/s today for 2k usd, the same company is selling pre-orders for a 3X GH/s machine for that same 2k usd in 3 months period (spoondoolies). So you have 3 months before difficulty increases and your mining rig decreases in value by less than half in a short period of time.

You're mostly right. It's profitable only with free electricity and stolen hardware. I looked for the cheaper GH/s per dollar and it's the Antminer S1 (that unfortunately goes up in price with BTC). But take into account the amount of space, cables, PSUs you'll need. With an SP10 you'll have the equivalent of 8 S1's using only 1.25U rack space. And with the increase in S1 prices, you'll end up paying 1.8 usd per Gh/s.

Current price is 2 usd per GH/s. For August, SP30 would be 1 usd per GH/s.

Mining is commoditized. Only massive farms with close-to-free electricity will be making a profit.

My advice? Stay away from Bitcoin from now. BTC price is +40% in less than a month and mining hardware is overpriced too. Bitcoin could go up another 40% but I wouldn't count on the bigger fool's theory this time.

But what mining rig has the best $/hash without taking into account electricity cost? Antminer S1 seems a decent one (1.33 usd/ghs without PSU).

Where you got those numbers? In coinwarz.com the estimate number is 0.0481 or 0.037 counting energy cost in my area. ROI looks more like 6 months than 1 year.

Seems like p2pool is better for bitcoin for it decentralized nature but having only 1% of the bitcoin hashrate doesn't mean the chance to find a block (and share it among it miners) is very low?

Hi guys.

I'm thinking about buying an Asic Miner (1000Gh/s). I checked coinwarz.com and with that speed, I'm (supposed to be) able to make 28 usd a day, or 23 usd counting electricity cost. That's an estimate of course.

Is that a realistic expectation? I know the difficulty increases and the profit decrease with time. My doubt is… how long should I expect to make no money out of the machine? Couple years?

I imagine I should join a pool.
-What should I consider when joining a pool?
-When I join a pool, the more I contribute (in hash power), the more my payout is?
-It's more profitable to join Ghash.io or p2pool?

Thanks in advance.

So a few hundred people could crash bitcoin price?

Best piece about the surge in bitcoin price. According to the article, huge demand from China.

http://marginalrevolution.com/marginalrevolution/2013/11/china-and-the-soaring-price-of-bitcoin.html

Yeah, send me your wallet to me. I'm a total stranger but you can trust me. /sarcasm

Do you use escrow?

EDIT: nevermind. Just saw the new prices. +50 U$$ above MTGOX average price for each bitcoin.

No, thank you.

Litecoin capitalization is around 50 million usd. Doesn't offer anything Bitcoin doesn't have.


Too many people saying where you should GAMBLE your money. Talk to a financial advisor. A good one will explain in a way you can understand.

I'm impressed by advices like "BUY ALL IN BITCOINS" and the such.

First reply was the best. Don't GAMBLE invest more than you're willing to lose. Bitcoin is not an investment, it's a currency.

I like love the concept but it's very volatile. Many people are hoarding the coins expecting to go up another 1000%. Let me give you an example.

George buys 10k usd worth of bitcoins. A year later that same 10k usd is worth a million. He has two options:

1- Cash in and RETIRE! With a million, he'll be averaging around 7% (70k) annually with a diversified portfolio. World markets could crash but the companies he invested in aren't going to vapor and stop paying dividends.

2- Hold his bitcoins expecting to be the next billionaire. It could happen…. OR NOT! Maybe a new and better crypto-currency appear, maybe the price crashes (with many more people cashing in to retire), it's too early to say. A selloff is bound to occur, could be tomorrow or in 10 years.


My advice? Buy 10% (7k usd) in bitcoins and the rest in conservative stocks with a good record of paying dividends. You might not become millionaire but you won't risk all your money.

And don't bother looking for mining stocks and other risky "investments". Those "companies" can run away with your coins in any minute. Some could vouch for it but it's the same as entering early in a ponzi scheme. You might get lucky and make a quick-profit but eventually someone gonna get hurt.
