비트 코인 <- 구글링 하다 알게되었습니다.
경기도 거주, 서울 직장...

rig은 윗분 같은 저런 장비가 있어야만 하는 건가요?
mining이 비트 코인을 얻는 방법이라고 하는 것 같은데...

많이 궁금합니다. ^^;;;

ㅋㅋ. 저두 경기에사는뎅~ ^_^

빗코인어떻게 아셨습니까?

애플포럼을 게시글 읽다가 누군가 써 놓은 글 보게 되어 알게 되었습니다. ^^

한국에서는 BTC를 모아도 환전 말고는 할게 없군요.

거기다 전기요금이 상당합니다.

반갑습니다~~

rig은 윗분 서명 같은 애플컴퓨터가 아니라도 가능합니다.

일반적인 PC이면 mining이 가능하고요. 가능하면 AMD의 고성능 그래픽 카드일수록 잘 됩니다.

문제는 전기를 너무 많이 먹어서 가정집에서 돌리기에는 무리가 따릅니다.

bw1213님 빗톡에서 뵙고 여기서 다시 뵙네요.

비트코인 채굴에 재미가 들려서 틈틈이 여러가지 시도를 해보고 있는데요.

처음엔 여러 대 돌리고 오버 클럭 하는걸로 속도를 올리다가
stale 적게 나고, fee 없는 마이닝 풀을 찾아 보다가..

지금은 프록시를 사용해서 자동으로 여러 마이닝 풀을 돌아다니는 방법을 연구하고 있습니다.
일반적인 채굴보다 수십 퍼센트 이상 효율을 높일 수 있더라고요

그냥 CPU로도 가능하긴 한데 너무너무 느려서 안하느니만 못하거든요;
bw1213님 말씀처럼 AMD GPU가 아니면 효율이 잘 나지 않습니다.

bithopper 수정중이신가 보네요.

쓸만한가요??

어차피 share되는 비율에 따라서 보상이 지급되는 형태라 hopping을 해도 이익을 볼수 있을거 같지 않은데,

어떤식으로 이익을 얻게 되는지 궁금합니다.

어떤식으로 이익을 얻게 되는지 궁금합니다.

PPS 방식이면 각 share 마다 보상을 주니, 이득이 일정합니다만

proportional 방식의 경우, 라운드가 일찍 끝날 수록 시간당 이득이 (당연히) 많겠지요.

그래서, 라운드가 막 시작되는 pool 로 hopping 한 뒤
일찍 안끝나면, 다른 막 시작되는 pool로 다시 hopping하는 것이 기본 원리입니다.

difficulty 43.5% 시점에서 PPS 풀로 hopping 하는 방식만으로도 평균 25% 가량 이득을 볼 수 있고요
(수학적으로 계산해둔 페이퍼가 있더군요 ㅎㅎ)

여러 proportional pool 사이에서 hopping 하면 두 배 가까이 이득을 볼 수 있습니다.

요즘 hopping 하는것을 방지 하기 위해서 일부러 block status 를 1시간 정도 지연하여 알려주는것 같더군요.

이런 상황에서도 가능한건가요??

지연하여 알려주지 않는곳은 hash rate가 너무 떨어져서 오히려 더 큰 손해를 보게 되더군요.
하루에 들어오는 양이 불규칙하고 심지어 하루에 1BTC도 안나오는 경우가.. -_-;;

말씀하신대로 stat을 지연해서 알려주는 deepbit이나, BTC Guild 같은 곳에서는 사용할 수 없습니다 -_-;
PPLNS 방식의 pool에서도 사용할 수 없고요..

하지만, 아직 사용할 수 있는 많은 다른 pool들이 있다보니, 바로바로 payout 하고 싶은 욕망만 제어할 수 있다면 쓸만합니다.

실제 성적을 뽑아보니 저는 평균 두 배 정도 효율이었습니다.

Hello Korean Bitcoiners!

Sorry I am writing in english, I do not speak Korean language.

I will come to visit your country in September.

I thought maybe it's a good idea to buy some KRW from local people there and save some exchange fees Wink

Does anyone want to buy some BTC for KRW in Seoul in the middle of September?

cheers,
molecular

haha. I'm in. You know I'm starting the Korean National Bitcoin Exchange? You'll be able to do that online pretty soon. Wink

What part are you coming to?

Seoul first. Will visit my girlfirend's relatives who live there, she's half-korean. After a week or so on Seoul we would like to travel around, do some hiking... will be there for 3 weeks.

I'm looking to do a cash transaction, buying KRW for bitcoins, so using your exchange is probably not practicable for me, since I would have to be able to get the cash out somehow...

Would you be willing to meet in person and make a trade? I would like to cash in maybe around 50 to 100 bitcoins (of course depending on the exchange rate in september). How would we determine the exchange rate, would you charge a fee?

Fees wouldn't be necessary, but I'd have to go by the KRW > USD > BTC exchange rates if that's alright with you. 50 to 100? I was expecting a much smaller number. No worries. Count me in for 25 for sure and I'll ask around my office for the other 25~75.




No fees, cool! No problem going throug KRW > USD > BTC to get the rate, that's fine with me. Likely still better than using my bank.

Please tell me when your exchange is up, so I can check it out ^^. Will it be an exchange that keeps balances and takes care of withdrawing / depositing or will it just be a "matching" site, where the users have to make the transactions themselves?

A side question: I've been trying to find out wether or not I could use my mobile (sony ericsson xperia hd mini pro) in Korea. It seems your GSM networks use a different frequency (2100Mhz). what about CDMA/UMTS,...
I'm sorry to bother you with this.. but maybe it's best to ask someone local. Is it possible to get mobile internet for 3 weeks cheaply in korea? I'd really love to be able to use google maps and translate while on the run. It would also simplify (make more secure) giving you BTC (ssh -> bitcoin sendtoaddress) any hints/ideas for a traveller?

Back to the transaction: 25 BTC is a good start. I don't need to exchange everything via bitcoins and I wont rely on it, obviously (fallback is to use options offered by my german bank or credit card to get cash).

Getting some cash from you and/or your colleagues would be awesome, though, so I could brag about it (hey, I use bitcoins paying for my vacation ^^) and also use it to advertise bitcoin as a way to get a hold of local currency.

first: thanks for the info on your projects, sounds ambitious and very cool! also thanks for the info on wifi (you're saying there's open hotspots everywhere? what more do you need ^^)

I'd almost like to buy all 100 from you just so you could say that to your friends. lol. my life right now is devoted to making Bitcoin usable everywhere. Instead of just trading Bitcoins in for cash directly, why don't you just keep a tab for 3 weeks and send me bitcoins and I can send you KRW whenever you need it? Seems like a much more frugal thing for the both of us, especially since my contract work pays me daily (e.g. It's easier to send you $100 a day when you're here then it is to send you $500 as soon as you get here), and you shouldn't be selling Bitcoins right now anway IMHO.

I don't understand... keep a tab? how would you send me $100 (in W cash) every day? You use paper money to buy food, pay hostel, etc, right? please explain.

P.S. Bitcoiners have to stick together. Your girlfriend probably has everything handled, but if you need anything when you get here, I'm a phone call away.

I really appreciate that! Would you pm me your contanct info?

I wouldn't go so far as to say no one uses cash here, but I will agree that the banking system is generally pretty good.

Post edited. I mispoke. We use cards quite a lot more than bank transfers. Just wanted to make it clear that unless you're shopping on the street, cash is not necessary. Also, since the banks will give you a debit card minutes after setting up an account, there is no real need to worry.

Well, maybe setting up a bank account really is the easiest way to go for tourists.

So is electricity more expensive than in the UK?
