If they decided to use BitPay again, I would rather continue paying with fiat on their platform. BitPay does not support the Lightning Network (since it's pro Bitcoin Cash) and has enormous "network" fee which is basically their markup. There wouldn't anything wrong in this if they called it something like service or conversion fee. BTCPayServer is a free and open-source alternative which supports both Lightning Network and on-chain transactions. However, I doubt that they are going to accept Bitcoin anytime soon again.

There is no need to use an exchange. Many of them have ridiculously high fees (mostly withdrawals) and force their users to pass through KYC verification. I would rather use Changelly or some other third party service which offers quick exchange between different cryptocurrencies. Even TREZOR started supporting these kind of services natively in their web wallet interface.

Their Telegram channel is full of people who are also against the recent change. Samoraui support replies that fiat display support is not going back to their wallet even if many people demand it. I doubt that anyone has an APK file of an older version, what a shame. It was really convenient for me to check how much USD equivalent in BTC I can spend on-the-go. I am going to continue using it since it's one of the best Android wallets I have used so far.

Actually, Lightning and other layers might be a good way to scale. Each of these solutions still forces their users to broadcast on-chain transactions at the beginning but this can be also partially fixed (channel factories). Lightning Network transaction fees are usually near zero. This will never be achieved on-chain due to limited block weight (long and controversial topic). It all depends on how you perceive Bitcoin. Either as a store of value or as a currency.

Think about the rest of the country. Imagine what would happen if an earthquake occured close to one of the biggest national mining farm which secures the national cryptocurrency. It would take some time before the mining difficulty adjusted. Transaction fees would become enormous and the time between each block would be too long to provide instant transactions (this doesn't apply to the Lightning Network on Bitcoin which works independently after funds are locked up in a channel successfully). It is government's duty to provide food supplies at such time.

You can skip this step and use a strong password instead. I have been using only passwords for a long time and nothing bad has happened yet. Here is how my public key looks like in ".ssh/authorized_keys".


Of course it would be better if you managed to get it worked out.

I don't have a text file either. You should still be able to access your Raspberry Pi by simply typing in only IP address in the host name. Use "nano .ssh/authorized_keys" to access your saved keys. Save it using CTRL + O. I copied my public key from the window in which I had to move a cursor a bit.

I followed the tutorial on my VPS and everything works fine. If this was a problem with the key configuration, you would get a "Server refused our key" error. Are you sure that you have put a public key in ".ssh/authorized_keys"? Make sure that your router hasn't changed the local IP of your Raspberry Pi. It may happen if you didn't configure it to be persistent.

There is a huge difference between the possible ways of using tokens and cryptocurrencies. When I went to Greece I was surprised when I saw a couple of places which were accepting many different cryptocurrencies for their service. I guess it's because they use a payment processor such as CoinGate which takes care of everything. Many people try to take advantage of the ICO bubble. Most of the tokens out of the market are useless because the same service could be provided without the token. Using tokens requires the user to know how to use cryptocurrencies (Waves, Ethereum, NEO and so on).

Yes, there is. Some distros have a LiveCD feature which allows you to test the operating system without making any changes to your PC. Create a bootable USB with the ISO you choose and boot from it.

Your problem is that your system doesn't know as which user you are trying to log in. The solution is quite simple. Enter "USERNAME@192.168.1.2" in the host name, add your keys and save your session again.

I would recommend him TREZOR since its developers are doing a great job. It doesn't support as many altcoins as Ledger but at least it provides easy to use and always working wallet interface. A few weeks ago, I wrote a list of hardware wallets which you might find useful. I would not recommend buying a hardware wallet if the investment is lower than a value of such wallet. As Omega wrote, Electrum is a good choice for beginners, especially because user doesn't even have to download any additional data. @MathGame you should check out my Electrum tutorial for beginners.

You got that wrong. What the author of the tutorial actually does, is opening a file (sudo nano etc/fstab) and then replacing "UUID=123456" manually. CTRL + O lets you save the file.

You can try this automatic installer if you find it too difficult to install it on your own.


Yes, you have to use nano which is a text editor as a person above mentioned. Use "sudo nano /etc/fstab" and save your file using CTRL + O.

I wonder if Electrum is going to support receiving funds over the Lightning Network. LND already supports "disabling" channels which means that the routing problem should not be present anymore. This solution should be implemented in Electrum as well in order to avoid the increase of offline channels which might cause problems while sending payments. I have just watched the end of the event's stream and it was mentioned that a new version with the Lightning Network support should be released in a few months. There is no need to rush.

Problems with elderly people are unavoidable; however, we should not leave them alone in the world which becomes more and more advanced. We should help them with understanding modern technology instead. I am not surprised that the Chinese government wants its people to use cashless transactions. It would make it easier for them to track the financial activity of their citizens. I am quite sure that the grey market will move to previous metals if that happens.

There are still many websites which allow their users to buy Bitcoin using a credit/debit card. I doubt that these kind of exchange differs much from an ordinary payment. I used this kind of service and I know that there are some limits if you don't decide to go through KYC verification.


Using BTCPayServer might be a good idea. As far as I remember, it even supports Lightning Network and altcoin payments. Great alternative to BitPay which has outrageous fees.

Developers of every single fork will have to take care of that issue on their own. Litecoin, which is a fork of Bitcoin, has already got its client patched. I wouldn't expect any reaction from the developers of, for example, Bitcoin Diamond, Emerald and any other Bitcoin clone which nobody uses.

@achow101 Do you happen to know why the minimum transaction fee is going to be lowered in the 0.18 release and not in the 0.17 one?

I guess that many people are still reluctant to use decentralised exchanges because these exchanges lack liqiduity and haven't been out there for a long time. There still might be some critical bugs which might lead to huge losses. Binance is one of the most popular centralised cryptocurrency exchanges right now. I am quite sure that investors trust them and won't hesistate to try their latest project. Let's hope that bisq won't have any problem with surviving after Binance Dex launches.

That doesn't mean that there won't be people who don't want to take responsibility for securing their own money. Wouldn't you feel much better blaming bank for the loss rather than yourself? Also, many people still have problems with some basic operations. This will change since current generation is used to technology but I can't imagine seeing my parents using the Lightning Network or simply signing a message using a Bitcoin address. I don't see anything wrong in such banks as long as people are aware of other possibilities.

Yes, you can. If you have your 12 or 24 word seed then you can use some other software, for example, Electrum. Here you can find a tutorial on how to do it. Note that the latest version might ask you which type of address you were using. It could be legacy (1...), nested-segwit (3...) or native segwit (bc1...). It looks like bither doesn't support SegWit so you have to select legacy type of address while importing your seed.
