Bitcoin has several advantages over other means as a store of value. They take no space. This means that you can store them in a USB as well as a backups online for example in an email. You do not need to pay anything for storing the Bitcoins. There is no need to pay for a secure bank account since they can be stored online or in USB or even in your brain ...

It seems obvious to me that this is a scam. No legitimate investment in the world can guarantee a rate of return of 20 percent per day. At that rate, with a 5 btc initial investment, you'd own all the bitcoins in existence after 81 days. And after 15 months, you'd have this much. But you may want to contact blockchain.info directly; there is a contact link ...

Disclaimer: At the time of this writing, I am a shareholder with ASICMiner. Also be aware that the Bitcoin stock market is, like Bitcoin, very immature and not regulated. The risks involved are far greater than for a traditional stock market. Like @Steven Roose just wrote, you can buy Pass-Through (PT) shares through two separate stock exchanges, BTC-TC ...

Volatility: The price of Bitcoins is fairly unpredictable. A speculator is basically trying to predict the future price of Bitcoins. Security: A speculator generally has to trust his Bitcoins and currencies to an exchange, at least some of the time. That exchange could disappear or claim he transferred out his Bitcoins. When his Bitcoins are not in an ...

Obviously, he is a scammer trying hard to look similar as the Blockchain's Official Investment scheme but there isn't anything like this ever before. Many scammers are there, one of the most luring advert is 'Earn through Bitcoin Mining from Antminer(S9)'. In the name of Antminer(S9) many persons reaching out through various social platforms to you and ...

Investing in expensive mining equipment hedges a bet that the return on investment, in the form of Bitcoin, will eventually pay off the initial investment and continue paying a return for some time before becoming obsolete (like CPU mining has and GPU mining shortly will) or breaking down. It may be possible operate this as a business, writing off expenses ...

A list of Bitcoin-related financial investment services: http://en.bitcoin.it/wiki/Trade#Financial

Yes, absolutely. Here's just one example of how this can happen: You invest Bitcoins worth $100 in some kind of high interest scheme. You cash out of the scheme and get Bitcoins worth $200. You invest those Bitcoins. You lose them. The high interest scheme turns out to be a Ponzi scheme. You are sued to clawback the $100 value of the Bitcoins that were ...

The moment new funds arrive from Dwolla, Mt. Gox will attempt to execute the remaining part of the order using ...

When you say "I won't have to worry about the security of my coins"... I think you've got this backward. There's nothing more secure than a paper wallet that has been generated offline. Bitcoin was created as a way to avoid the need to trust a third party. If you don't believe that's necessary, then you're just trading it hoping to make USDs, not because ...

A hash is a function that takes a string as an input, does a transformation of it, and returns a second string that's considerably shorter than the original and that could be considered is the "resume" of the original. You can check Wikipedia's Hash definition Hashes are required for "mining". I'm new to Bitcoin so I may describe this wrongly: As part of ...

Mining was never supposed to be profitable. And it's a derivative of bitcoin which is already risky speculation. Don't add the extra, annoying risk-without-an-upside of wondering whether BFL will ship your machine in time to turn a profit. Even they state that there's no guarantee that their machines are profitable. If you are sure that the price of ...

Build in a reliable entropy function to take account of natural decrement in value over time. All value degrades in nature, and this is the fundamental problem with money in that it can be hoarded without cost. Not sure how this would be implemented, it does dig at the root of the basic theory of money and value but that is what we are attempting to achieve ...

Key points in bold. Hoarding doesn't need to be prevented. At least, not yet. See this answer for a solid argument: How does hoarding hurt Bitcoin? Bitcoin attracts hoarding by design. To change that would turn it into something else. As Bitcoin matures, I expect that it will remain a problem that speculative trading brings instability to the market, ...

On the whole, there is no minimum investment for Bitcoin, as it is not a security such as an ETF or mutual fund purchased through a brokerage or management firm. What minimum purchases exist on Bitcoin exchanges are merely requirements set by each individual exchange to reflect the minimum purchase/sale that they feel is necessary to cover their overhead ...

Most of these so called pump and dump groups are illegitimate or downright scams. They usually only work for the inner group and the promoters who want to get you to join. The scam works by buying the coin a few days earlier and then announce that you should buy the coin at a later time...the people like you try to buy the coins and then the promoters dump ...

I speak from the point of view as a middle-aged (Born 1968) investor; I think the answer to the question is quite simple. You cannot simply consider the start point and end point in asking the question. Along the way the price will gradually appreciate and most people have a price at which they will start to sell their Bitcoins. Currently I hold about 630 ...

It isn't too hard to find someone willing to sell large amounts of BTC at around the MtGox market price with no fee. You can try #bitcoin-otc or the Bitcoin Forum's "Currency exchange" section. Wire transfers and Western Union are the most commonly-accepted transfer methods for large amounts. It's also very easy to buy MtGox USD coupons. A lot of sellers ...

There is plans to implement conditional transactions which would do some of the things you indicated. That hasn't been implemented yet. To do what you want would require creating website from end. For example you could display current balance & goal as well as the number of donators. When someone donates you could have them provide a "return address"...

For me the Best solution is to mine Scrypt based currencies like Litecoin etc. You can mine them easily with common Graphic cards which are easily available. You can than trade these currencies for Bitcoin if you want. It will probably take more than a year before first Asics for Scrypt will be available. So you still have some time left. Even when asics ...

For $2800 (the price of Monarch 500GH/s, as of 23 Dec 2013), and $4680 (the price of Monarch 600GH/s, same date), you might as well purchase a 1TH/s mining hardware, such as from VMC, or CoinTerra. The other alternative is to use these mining hardware to mine some other altcoin, instead of Bitcoin, and hope that the other altcoin would come to prominence ...
