Buying coins by yourself is the best investment options since you don't need to rely on a third party to handle the coins for you, thus no risk of default
I do own a couple of coins myself. I was asking to know if there was any movement in this direction since it could have huge implications for the coming price moves in bitcoins as well as its respectability.

I am beginning to think that Bitcoin is a project by U.S. intelligence agencies to cognitively infiltrate Austrian economic enthusiasts by way of educating them about how things got to be the way they are.
What lessons are being learned exactly? Well, for one, that quantitative metrics matter. It is not sufficient to make a projection to extremes based on the limited understanding of a theory. This is important for understanding little things like when you can apply linear relationships and when you have to apply exponential relationships... Little things like that. For another. Market systems are more complex than you might expect if the only model you have for them is a cartoon. It is insufficient to simply dismiss things you don't agree with as 'externalities'. One thing we have learned very well about risk management is that externalities and complexities matter. Isn't it a bit judgemental to think that all members in here subscribe to just one economic theory? I wrote this a long time a go and I also had my fight with the pure Austrians: https://bitcointalk.org/index.php?topic=160227.0

Not much going on in here so I might as well throw this question out: If you want to buy for a large amount, say between $ 50k and $ 200k, what is usually the be way to buy them on the exchanges?
By announcing on a public forum when you're going to buy and at what price you're prepared to buy. Posts on this thread such as, "Wow, get ready for the big one," will suffice just fine though. I can't see what all the fuss is about. I trade bitcoins for my customers but I do not currently need to buy this kind of amount. I might in the future, though. Might as well arm myself with some knowledge.

I have moderate experience in buying such quantity from an exchange. It is difficult to give good advice, because it depends a lot on the exchange, the general mood, and the players in the exchange. If there are big sellers watching, it may be good to set up a wall near the market, this will induce them to sell without slippage for both. This approach may, however, be detrimental in boom days, where a big bid wall just prompts other bidders higher. If you dare to bring scarecoins to the particular exchange, it is possible to pretend to be on the sell side with big walls, while actually purchasing nimbly. Even more aggressive tactic is to batter the price down with a supposed flood of coins (very few of which are actually for sale though) and purchase 5-10% cheaper. Before doing anything creative it is important to familiarize yourself with the exchange in question, plus the market situation. Sirius Money looks good. +1 Thank you! Good to see you back online. How is Hopea doing?

We have all heard about the Winklevoss' plans to start an ETF but do you know about any other investment companies/capital management companies that have invested in or plan to invest in bitcoins?

Visa and Mastercard are upgrading EMV to use an ECDHE handshake between card and terminal. So regular credit cards will be able to do at least some EC crypto soon.
However those card chips are proprietary and cannot be programmed.
It's the wrong model for Bitcoin anyway. Look at the Trezor instead.
Why is it the wrong model for Bitcoin? The good thing about is that customers are used to smart cards and POSs. And a correctly designed smart card can, in the POS, do exactly what Trezor does.

A card chip can do it.
The card I use however uses a cryptographic co-processor to do the signatures so the cheapest cards usually cant do it.
It takes less than a second, though I did not time it more exactly than that.
Thank you for your answer. That sounds very exciting! Do you have a link to a report or some numbers where I can read more about it? Edit: Just found your thread on this. Will be reading up on it.

I do not know how much a bitcoin credit card has been discussed on this forum. By a bitcoin credit card I mean a credit card containing the private key (encrypted of course) capable of making and signing bitcoin transactions to the network such that the chip itself calculates the writes the transaction and signature and the transmits it to a credit card terminal (POS) into which the credit card has been inserted. A search on this did not reveal anything. A transaction needs to be signed in order to be valid. The signature is calculated from the private key and some kind of hash(?) of the transaction using the ECDSA (Elliptic Curve Digital Signature Algorithm). My question is: How computationally expensive is it to sign a transaction and specifically, do you think that a chip on a credit card would be able to perform this calculation? I am thinking about normal credit card chips which follow the ISO standard 7816 and a standard called EMV. I believe that this is the chip being used in most credit cards: http://www.maximintegrated.com/datasheet/index.mvp/id/2949As far as I understand, these chips already perform other kinds of encryption calculations like triple DES and RSA: http://en.wikipedia.org/wiki/Smart_cardMore information on the interface can be found here: http://www.maximintegrated.com/app-notes/index.mvp/id/4029tl;dr: Can a DS5002 Secure Microprocessor Chip calculate 256 bit ECDSA?

The BS to real information ratio isn't complimentary.
The point is to give newcomers to Bitcoin an idea about what to consider. I am not interested in going into ECDSA, ripeMD160, or SHA256. But if you have any suggestions for improvements I would love to hear it. What relevant information for newbies do you suggest that I include?

Hi I have written some security recommendations on the use of bitcoins. It is a very basic introduction to Bitcoin security but I would like your feedback on it. The security recommendations can be found on Sirius Money's webpage here: http://www.siriusmoney.com/sirius-money-security/

The solution is green address.
Actually the solution is to not worry about it, it is really just another form of shoplifting. People who want to steal will find a way, and going through the register line is a bad way to do it because most places you will be caught on camera and eventually caught by law enforcement.
But double spends will be rarely attempted and I suspect the losses will likely be less than what is currently lost in debit/credit card transaction fees and chargebacks.
True. Trust and then Green addresses which is another form of trust. And green addresses are not a problem for the decentralized idea of bitcoins since they are based on trust and not mandates.

WOW a lot of bitcointalk accounts are getting compromised. Theymos 2FA is need! I got some emails from Yahoo saying my email had been accessed from Russia. And later I got some info about a verified btc-e transaction. All clues point to btc-e imho. Please quote OP in another thread
