I see. Scratch means it has to be in physical form, already. I thought that I could print it myself in DIY style hehe. In this case, could you elaborate this "I can even mail the card if you like" to me? Like how you e-mail a card that's in physical form and cannot be digitalized without ruining the fun of scratch.

I could do this for you, but to tell for sure, I have to know your imagined rates, haven't I?
You can PM me if it is not public, but consider please the suggestion that publishing more info will help you receive better offers.

Sounds to be a great gift for your gamer relatives/friends!

How should I imagine a physical Steam gift card? Does it contain some kind of code that I can submit on Steam to download games?

Excuse my lack of knowledge, but I have not played on Steam for years, but in fact, I have a couple of friends who love Steam and eager to buy or get Steam related gifts.

...and the best advantage is exactly there. This bot could COMMUNICATE with the user so the user would not need to write long command code for complex queries, just type to the bot what she/he wishes to see. The bot will adapt to the user and will not require any studying before usage.

Since I am doing a several-month research about DBs at Uni and I have some knowledge about blockchain already, I had the realization that how cool it was if you and I had a knowledgeable friend next to us when we have to query the blockchain. How comfortable it would be if all we had to do was just asking our friend to get certain information for us and he knew it by heart and did it in lightning speed.

So, what if I combined an A.I. and blockchain and provide the knowledge of the A.I. to beginners via a comfortable communication protocol?

For example, it would be possible to simply text the A.I. "Hey, you know my BTC addresses. How much BTC did I sent overall in the last month?" and similar functions.

What is your view on it? Would you use it?

Thank you! Very good thread, VultureFund! I hope it will help me in the future too. As a matter of fact, I am deciding whether I will invest into an altcoin or a higher level BTC project next. As some of the posts suggested, choosing a high level BTC project over an altcoin or simply keeping my funds in BTC may be a more stable option. I am closing this thread for the time I decide what to do. Maybe, I will return to it once I choose an altcoin investment.

I thought I could invest some more money into an altcoin, but my problem is that I cannot afford in time to follow the development/prices regularly. That is why I want to invest into an altcoin that has a relatively stable rise in price and I do not mind if this rise is relatively slow. So, what altcoin investment would you recommend for me if I want to invest for long-term?

Looking through the year 2016, in your opinion, what was the most important update in the BTC network? When writing update, I am meaning technical update and although I am asking your personal opinion here, also I want to know why you keep the metnioned update the most important.

1) What sources do you mean? Forums, freelance communities or company sites?
2) I usually do that, but sometimes you did not have such a project beforehand or had it under different circumstances.

I am hearing the problem of starting up where everyone starts as "untrustworthy", but since it would be implemented above the BTC network, for example in an online community, members would have the chance to upload proof and the reponsible Staff could check it so members will have the chance to build up their ratings. For example, you are not forced to link your driver ID to your BTC address, but if you do, that certainly should increase your rating and prevent "rating up yourself" since you have only one valid from certain IDs.

Cool. Is that your project or did you build a project that used the mentioned project as something like an API?

At a 450-GB DB I think queries could be optimized up to less than 1 minute speed with your home gaming PC.


It depends on the use-case then because in some DBs there are frequent delete operations. But I agree that most DBs are not like that so the possibility is worth to take into consideration. The question is how much it would increase the necessary space and the issue of SRP because even though rollbacks are infrequent operations, when they need them they usually need them ASAP.

I think that it will never happen because BTC is an alternative currency. Alternative to what? Fiat. In my opinion, the current fiat international currency is USD because people accept it all around the globe. Even in Russian or China. Not counting the many online payment processors that you can do international transactions with and which processors always have USD as option. But BTC is an international ALTERNATIVE currency, which it already is 

Correct me if I misunderstood something, but would not that require a MUCH bigger size of HDD? In addition, the log writing and reading speed would significantly increase that would result in slower DBs, would not it? At large DBs, speed is essential because some queries could take up to 20 or more minutes even without the mentioned idea.

The reason why this discussion is in the Project development section instead of the Development & Technical Discussion is that the rating system would run at a higher level than BTC so you, in fact, could ignore the rating and proceed with the BTC transaction. It would expand the information you have about the context instead of taking the feature away.

Thank you for your reponse! Even if you cannot see the individuals in blockchain, you can see the entities. Entities of high reputation may be considered more reliable than entities with poor reputation (I do not say scammers, but without transaction history of positive feedback). It is like you would do an exchange with an entity that has excellent history on Bitcointalk over someone who has just joined even though you do not know the individuals behind the accounts.

I see what you wrote as a throughoutly designed estimation method. I think, it could look well even in a documentation. Do you have a formal calculation method for that, a formula for example, or is it still informal?

I am using the business software ADAPTO and it has a module of Risk Management. From my experience in this tool, using a risk management tool truly takes special course to advance. Your business area seems to be a very risky one. May I know what tools do you use to manage your risks?

Hey!

In my experience, every exchange company (even individuals) takes risks into consideration and most exchange companies in crypto even has some kind of risk mangement system, totally informal at most of the times and without any documentation, though.

Do you use or have you ever met with any (documented) risk management system that worked well in crypto exchange?

If you are in a business in exchange, how do you manage the risks in this highly uncertain area?

When a client seeks you with an offer and asks how much it will cost, take in time ... etc how do you estimate these parameters of your project?

Do you use any decomposition (if yes, what is your technique?) or do you estimate by your past experience? Do you use a standard technique by any chance like LOC oriented?

I know about the advice, but I know about also people link their identity/organization to addresses in certain cases. Charities, for example. On a site where the seller person is willing to link his identity to the product/service that he is selling, what is the argument against losing privacy?


Were you writing about blockchain ( . ) info? If so, you could always use your old addresses as well. You may give one of your previous addresses to the seller and you still will see the received funds in your wallet. For your privacy, it is advised to use a new address for each transaction. That is why the site automatically generates them for you. However, you may see my example above to get a case when a person is willing to use the same address with good reason.
