제네시스 마이닝은 클라우드 마이닝 (위탁 채굴) 서비스이다. 이 서비스를 이용하여 직접 채굴 장비를 운영하지 않고서도 비트코인, 이더리움, 라이트코인, 모네로 등을 채굴할 수 있다.

 

(참고) 이더리움 시세:

 

 

 

1. 제네시스 마이닝 사이트 접속

https://www.genesis-mining.com

 

 

 

 

2. 가입 버튼을 눌러서 가입하기

이메일만 있으면 된다. 참고로 로그인 할 때마다 reCAPTCHA로 이미지 판별 문제를 풀어야 한다. (로그인 brute-force 공격 방지?)

 

 

 

 

3. "해시파워 업그레이드"를 눌러 해시파워(채굴 능력)을 구매한다.

 

참고로 이더리움 55 MH/s는 최신 그래픽 카드를 장착한 개인 PC 2.5대 정도의 채굴 능력이다. 채굴을 하기 위해 고성능 PC를 구매하는 것보다 효율적이라고 생각된다. 전기료도 안 나가고 열도 발생하지 않으니 더 효율적이다.

 

 

 

4. 결제는 신용 카드가 기본으로 선택되어 있지만, Bitcoin, Dash, Litecon, Dogecoin 으로도 가능하고, 가상화폐로 결제시 구매 완료 처리 속도가 빠르다.

 

 

 

5. 다음에 나오는 프로모션 코드에 WJ0CtL를 입력하면 3% 할인을 받을 수 있다. 손해가 가는 것은 없으니 입력하여 할인을 받도록 한다.

 

 

6. 결제는 입금 주소에 30분 내에 입금을 하면 처리가 완료된다.

 

 

 

 

7. 결제 완료 후 "대시보드"에 가 보면 아래 안내 문구가 나온다. 최소 24시간 이후 첫 지급이 이루어진다. 다른 일을 열심히 하고 돌아와 보자.

화폐 공급량 을 Ripple 사 가 결정한다.


결제 네트워크 (은행 등) 이 XRP 만 을 사용한다는 보장 이 없다. 고유의 토큰 (in-house tokens) 을 사용할 수도 있다.

Bitcoin Is Evil

Bitcoin Is Evil

It’s always important, and always hard, to distinguish positive economics — how things work — from normative economics — how things should be. Indeed, on many of the macro issues I’ve written about it has been obvious that large numbers of economists can’t bring themselves to make that distinction; they dislike activist government on political grounds, and this leads them to make really bad arguments about why fiscal stimulus can’t work and monetary stimulus will be disastrous. I don’t, by the way, think that this effect is symmetric: although people like Robert Lucas were quick to accuse people like Christy Romer of fabricating macro arguments to support a big-government agenda, this didn’t actually happen.

But I come now to talk not about macro but about money — specifically, about Bitcoin and all that.

So far almost all of the Bitcoin discussion has been positive economics — can this actually work? And I have to say that I’m still deeply unconvinced. To be successful, money must be both a medium of exchange and a reasonably stable store of value. And it remains completely unclear why BitCoin should be a stable store of value. Brad DeLong puts it clearly:

Underpinning the value of gold is that if all else fails you can use it to make pretty things. Underpinning the value of the dollar is a combination of (a) the fact that you can use them to pay your taxes to the U.S. government, and (b) that the Federal Reserve is a potential dollar sink and has promised to buy them back and extinguish them if their real value starts to sink at (much) more than 2%/year (yes, I know).

Placing a ceiling on the value of gold is mining technology, and the prospect that if its price gets out of whack for long on the upside a great deal more of it will be created. Placing a ceiling on the value of the dollar is the Federal Reserve’s role as actual dollar source, and its commitment not to allow deflation to happen.

Placing a ceiling on the value of bitcoins is computer technology and the form of the hash function… until the limit of 21 million bitcoins is reached. Placing a floor on the value of bitcoins is… what, exactly?

I have had and am continuing to have a dialogue with smart technologists who are very high on BitCoin — but when I try to get them to explain to me why BitCoin is a reliable store of value, they always seem to come back with explanations about how it’s a terrific medium of exchange. Even if I buy this (which I don’t, entirely), it doesn’t solve my problem. And I haven’t been able to get my correspondents to recognize that these are different questions.

But as I said, this is a positive discussion. What about the normative economics? Well, you should read Charlie Stross:

BitCoin looks like it was designed as a weapon intended to damage central banking and money issuing banks, with a Libertarian political agenda in mind—to damage states ability to collect tax and monitor their citizens financial transactions.

Go read the whole thing.

Stross doesn’t like that agenda, and neither do I; but I am trying not to let that tilt my positive analysis of BitCoin one way or the other. One suspects, however, that many BitCoin enthusiasts are, in fact, enthusiastic because, as Stross says, “it pushes the same buttons as their gold fetish.”

So let’s talk both about whether BitCoin is a bubble and whether it’s a good thing — in part to make sure that we don’t confuse these questions with each other.
