I doubt you'll find it in a shop in Singapore. https://www.buytrezor.com don't ship to your country? They do ship to Singapore however, so you could ship it to somebody you know there or the hotel you'll be staying at.
82  Bitcoin / Bitcoin Technical Support / Re: Do You have a Bitcoin Full Node running (24/7)? on: September 23, 2015, 01:08:05 PM

What is the minimum setup to run a full node on Linux ?

What is the minimal hardware I could use ?

I cannot use my laptop any more, no more drive space, too slow when I work and I have to turn it off at night.

Some people use a RPi (or similar spec'ed hardware) with an external harddrive. So much for minimum specs.

raspnode.com/diy.html
http://www.hardkernel.com/main/main.php
https://getaddr.bitnodes.io/hardware/

However the argument is, if you're actually helping the network with such a low spec computer, as it is slow with the tx forwarding (IIRC).

84  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: September 21, 2015, 02:17:28 PM

Feature request: Under Settings -> Currency, can we get "None". Sometimes I do not want/need the exchange rate displayed.

yes, this is planned for the next version. you will be able to select any number of fiat currencies, including 0.

I know work has been done on this since the above, but I still would like a currency option "none". That way I could cycle through USD, EUR, "none", depending on the situation. I realise I could go in the settings and remove the ticks, but it is rather tedious.

Anyone here uses Hive Wallet. I haven't been able to check my wallet via the web or app. Want to check if others have had the same issue.

[...] How about deleting peers.dat forcing bitcoin-qt to generate a new list?

That also works (let the software shut down properly before deleting), although there is a slim chance that all the "fresh" ones you receive are duds. It's better to addnode= at least one known good node. Some other lists with nodes you can consider to try:

89  Bitcoin / Bitcoin Technical Support / Re: Best OS to run a node? (not sure if correct board) on: September 20, 2015, 04:52:35 PM
So from what I've understand here, I have to pay something in ubuntu to make it more functional, right?

No, you get the same functionality. It's just that if something breaks you can (provided you pay for a support plan) just pick up the phone and immediately get support.

On that note, I've started using Ubuntu 3 years ago (personal laptop / nodes) and never felt the need to call. The argument is also about this: https://www.debian.org/intro/free . I'll be switching one day, I guess.

I like your project, android app with qr scanner would be a good point

Agreed.

Also, is support for xpub planned for? It works for search, but not in the watcher.

Basically I'm looking for something like the below, but with multiple xpub capability.
https://play.google.com/store/apps/details?id=com.alarmred.bitcoinbalance&hl=en

Thanks

Yes, xpub in watcher is planned.  More exciting stuff is coming up.... API .. push notifications on mobile. Keep tuned
By the way multiple xpub search works...and our site is mobile friendly too... try it out !

Sentinel is a good example. Try to implement something like that.

I agree Sentinel is looking good. However I'd like to add several xpubs. A merge between Sentinel and Bitcoin Balance would be ideal. Do you know how to contact the Sentinel devs?

I don't care about mobile friendliness in a browser so much. I'd rather have a one tap app, instead of having to: open browser, navigate to the page, login, etc.

94  Bitcoin / Bitcoin Technical Support / Re: No block source available. With active connections. on: September 20, 2015, 05:16:32 AM
Find a recent IP list of nodes and try this:

launch with bitcoin-qt -connect=IP

from terminal. A single IP. You will have a single connection, but since you can only sync with one anyway it does not matter. Launch regularly when done sycning.
[...]

IIRC, this procedure is not necessary any more with Bitcoin Core >0.10.0, as it gets data from multiple peers now.

Would also recommend Mycelium wallet.
I also use Blockchain, coinbase and xapo but none beats the security of mycelium when it comes to mobile security.

I'd say that any wallet that supports multisig is more secure than the ones that don't. Mycelium doesn't.
97  Bitcoin / Bitcoin Discussion / Re: Good Mobile Wallet? on: September 19, 2015, 01:10:45 PM

https://copay.io/ works on most platforms, so you can use the same wallet on different systems.

Schildbach's wallet is a classic, and it does not rely on a SPV server. It claims to be proper peer too peer.

Does anyone have a copy of the code? I'm trying to build something similar.

I thought I did, but turns out I didn't  Undecided . All I can find for gistfile1.py (posted Jul 6, 2015): https://www.snip2code.com/Snippet/576729/chainsnort-0-484--latest_stable-

It's integrated with certain banks so trades can be nearly instant.
banks ? if you dont care about anonymity or privacy then why are you avoiding coinbase ? it takes some days though..

Coinbase also seems unavailable in Germany: http://btcgeek.com/coinbase-expands-14-countries-leaves-uk-germany/

Alternatively to bitcoin.de (which is person to person) you can look at Kraken. They use the same banking partner as bitcoin.de (Fidor bank).

It seems to be the law in Germany that exchanges only can operate if they have a local banking partner, as explained in this (German) article:
http://www.winheller.com/bankrecht-finanzrecht/bitcointrading/bitcoin-exchange.html


Additionally there is a German section on this forum: https://bitcointalk.org/index.php?board=16.0  There might be more info available there.
