Gold and bitcoin have one commonality: they are scarce.
The scarcity of bitcoin (in the long run) will be larger than that of gold. Gold is being mined each year more and more.

Both bitcoin and gold appeal to people who would want to preserve the value of their (fiat) money. They serve as a store of value.
Again, in the long run, bitcoin is better. Bitcoin will relatively soon become a totally deflationary currency.

Bitcoin is also much easier to handle. You can transport it easily. You can store it easily. Unlike gold.

Not too hard to guess which one will win in the long run.

Thanks for explaining this. I think it is an important point to emphasize, so the users of your notes can feel protected.

And, good luck with your project. I hope it can help promote and popularize the usage of bitcoin, which can only be a good thing.

What I was able to deduce from the linked article in the OP, your note is suitable for users without any technical knowledge regarding Bitcoin and the underlying technology.

You say that the private key is stored in the card itself, and your app will connect to the Bitcoin network to check the balance or use the funds.

What I'm interested in is how you plan to protect the users' private keys (even from employees of your company)? This is important, even though the value stored on these cards is not so big.

One clear benefit (there are other benefits too) is that you don't have a regulatory entity.

Bitcoin and the other altcoins are decentralized currencies: they eliminate the need to have an intermediary, one central entity which regulates everything.

In line with that idea, why would you need a centralized exchange where there is a third party that regulates everything related to exchanging currencies?

Decentralized exchanges are certainly the future step to eliminate this unnecessary intermediary.

Do you really think this is possible? With the current market cap of $800 million, 50x growth would mean a market cap of ~$40 billion. This would put BTCP slightly above Ripple and Bitcoin cash . I know that this coin has a solid foundation (at least the technical side of it) but I'm not sure if such a growth is possible.

Pretty cool setup. I guess you have to do something like that if you live in a flat with limited space. I didn't take a look a the video, but when I checked the photo, noise was the first association I had. Hopefully no one sleeps in that room.

Thanks for sharing this, I didn't know such a project existed. Really cool concept, and I'll definitely keep an eye on their token. Tied to bitcoin indirectly, I don't see how this could be a bad choice. Of course, we have to wait and see how the realization goes.

No, definitely not. Only certain publishers (or ads) are checked manually. I think they don't have the manpower to check them all. From what I can tell, certain ads get triggered when certain keywords are present in them. These ads are then put on hold until someone checked them. Given Google's recent announcement that they will effectively ban cryptocurrency ads on their platform, it's really a surprise that they do nothing. This is something they can implement easily.

That's a good point. But on the second thought, that's how all the trouble started in the first place. People want someone else to be in responsible. Someone else they can complain to. They put their own responsibility to safely keep their funds into the hands of centralized institutions. And the centralized institutions count on this immature behavior of their customers and even abuse it to the extreme. Hence, the position of our society as a whole with respect to money. The monetary power is concentrated in the hands of the few.

I really don't know what these types of articles really serve for. If you read a bit into it, here is what it says:


Such claims really annoy me. As if their precious credit cards haven't been hacked many times before. Speaking about hacking, each time you make an online purchase with your credit card, your number and pin are being transmitted along with your private data. Unlike Bitcoin, where you keep your private key always safe by your side.

In fact there will still be blocks to mine, because without new blocks there would be no possibility to record new transactions in the blockchain. However, there will be no reward in the form of coinbase transaction (the first transaction in the block included by the miner to collect the block reward). There will only be a reward as a sum of all transaction fees included in the newly mined block.

It is interesting because if I understand the article correctly, they will combine their mobile Forex trading platform with cryptocurrency trading. It seems perfect for wider adoption and popularization of cryptocurrencies. The only thing I don't like is their name, GMO. It brings associations of some not so healthy types of foods.

It definitely looks like a network connectivity error. This happens to me when the pool is down for whatever reason. But if it happens consistently for various pools, than you should look elsewhere. Some suggestions to locate where the error is: 1. try changing the miner or changing the parameters of the miner and 2. try without overclocking if you have any in place.

As Lisk is already listed on a number of big exchanges, I'm not sure how much listing it on Cryptopia will change its position. But than again, it certainly won't hurt. Other than that it's a rock solid coin. Btw, it is really interesting that it's written in javascript. I wonder, could this imply easier building of app for the internet?

I agree that privacy is important, and I get the advantages of zk-snarks, but what's wrong with the current privacy altocins, such as Monero. Why do we need Bitcoin Private as a double fork of both ZClassic and Bitcoin? With all that happened recently around some of the leading figures of Bitcoin Private, I have yet to be convinced that it wasn't done for a short term monetary gain.

I checked the article and one sentence caught my eyes. The guy claims that by the end of this year BTC will be something like $20K whereas ETH around $15K.
To my mind this is highly unrealistic. Look at the current ratio ETH/BTC=0.078 What could happen for it to jump nearly 10 times and go to ETH/BTC=0.75?
Not much. Unrealistic to say the least.

This can be a very good option for beginners, but the downside is that Nicehash has a minimum minimum threshold for their payouts. You would have to wait some time (depending on your hardware) for the BTC to be accumulated and sent to an address you control.

If you don't want to wait, as others said, you simply go to https://whattomine.com/  or https://www.crypto-coinz.net/crypto-calculator/ or https://www.coinwarz.com/cryptocurrency or some other similar online service.

You enter your GPU model or the hash-rate of your GPU for the selected algorithms, and you have a clear picture what to mine.

Very cool, thanks for the tip. Had I known that, it would have made my life much easier while writing this post.


Thanks a lot, ETFbitcoin. And thanks for mentioning CSPRNG. It is important to know that the pseudo-random generator used in wallets of this type is secure. The atmospheric noise was just for demonstration, a simple way for me to select some entropy without going into other aspects of the problem.

I'm sorry to say, but TradeSatoshi is not the best exchange there is. I've been using it in the past, because some of my favorite coins were available there. I don't mind the outdated software they use to run their website, but I do mind some other thigs.
So here are some tips:

1. check upfront the withdrawal fee.
2. check upfront he minimum withdrawal amount.
3. be prepared to wait for you coins to be deposited or withdrawn (sometimes it may take a lot of time).
