Since you are writing using C# , you could use Xamarin [ http://xamarin.com/ ] (for both Android & iOS) and you don't have to own an android phone , Visual studio will allow you to run an Android emulator once you execute the code and you could test everything on it (It's going to require a decent RAM & CPU).

I found this which is fully written in C as you requested : https://github.com/matja/bitcoin-tool  (All commands are explained so It shouldn't be hard to use) , just make sure to read the disclaimer at the introduction part though.

Logically It's not possible to predict the price , at least nothing accurate as you are asking otherwise everyone would be rich by now. (this is valid for both fiat and crypto currencies)

Looks good , as far as I know you guys are the first who provide an API (for a mixing service) , you may want to contact Blockchain.info (since they dropped their SharedCoin i guess) or Blocktrail.com (btc.com now) to work together .

I'm not sure when you posted that account for sale , but If you posted it since a few hours , you should let the buyers know as It could banned anytime. (the name of your account is visible in the first picture and hidden in the others)

I'm unable to play the sound in the link you gave me but unless users will have full control over their private keys , I don't support the idea, reversing transactions is also another thing that shouldn't be in BTC.

for me , trading Bitcoin face to face kinda defeats the whole purpose of bitcoin or crypto currencies in general which is staying pseudonymous .
Trading with individuals in the currency exchange section (here) with the known payment methods sounds fine to me , If you want to stay untracable all you need to do is use HD wallets (as they generate new address each time you want to receive Bitcoins) or receive bitcoins directly to exchanges and then withdraw (It could be considered as a Mixer , but a free one )

I personally receive those emails in both Bittrex and Poloniex  , If you got it then It means someone logged into your account and It can't be a bug that simply contact users with no reason unless they screwed up.
Other then that , you may want to use https://bittrex.zendesk.com/hc/en-us/articles/201289914-How-do-I-enable-two-factor-authentication-2fa- for an extra layer of security.

Hi guys , I know that Virwox.com level 4 is on-request only but I want to know (If someone already did it) how to proceed ? do you need to contact them and tell them that you want to upgrade your account ? Is there is any minimum amount of transactions you should  do before they upgrade you ? or once you are level 3 , they could upgrade you with no questions asked ?

Yes , they are only giving MasterCard for physical cards though so you should order a virtual one (the Visa card) and link to PayPal , that way you could withdraw funds from PayPal to the card (and can buy BTC later using those funds)

Is it normal that I only see how much peers I'm connected to when I launch Ethereum wallet while there is  nothing about blocks/blockchain ? I'm almost sure that the downloading is finished as last time I checked It was like 2,444,000+ but the GUI can't seem to popup or anything ?   does it have anything to do with the new attack  I hear people speaking about ?
also , when we should see the ICN issued ? the test thing happened or not yet ? each time I go to school and comeback , I see shitload of pages added in this topic so kinda confusinge

Compared to when I posted this thread , It seems like the forum is more stable. In the meantime ,  I will keep the topic open In case theymos have some explanation for this.

Yes It's possible as well , you could go to the "Buy Bitcoin" tab or here : https://www.e-coin.io/buy (once you are logged in) and buy BTC with the card funds. (the minimum is 0.01 BTC but that shouldn't be an issue since you are buying +9$)
Now , If you want to transfer them into another Bitcoin address you control then you could go to https://www.e-coin.io/transfer .

It's possible to deposit as low as you want using BTC , but If you want to load the card then the minimum is 10$ . There is another solution (which I never tried but  It should work) which is withdrawing the funds from PayPal to the card , I don't think the limits will apply in this case.

Should everyone be apart from the test to be able to receive the real ICNs later ? or If this test works for a few people means that It will work for everyone else ?
Also , you said before that those who fail to put their addresses in their accounts , will be able to hold their ICNs in their ICONOMI accounts , If they suddenly decide to withdraw the ICNs from the account (after ICNs are issued) , would the withdrawal will be instant or we should wait hours/days/weeks ?

It's simply impossible , "Bitcoin bank" defeats the whole purpose of using Bitcoin in the first place. Banks wants to take control over customers accounts (including the fees and interest rates) and freeze them whenever they feel like it while Bitcoin is totally the opposite.
Services that control your private keys could be considered as Bitcoin banks as well and shouldn't be used (this apply for both debit card services and "wallets/exchanges")

Make sure you are connected to a server and It's stable , If you are not or the current server is lagging then try to change the server by clicking the colored icon at the bottom.

The new wallet is kinda hard to use but once you get used to it , you should be good to go.
Blockchain released a blog post 4 days ago : https://support.blockchain.com/hc/en-us/articles/207746403-Addresses so just check the "Import addresses" part , you will be able to import either a private key or public key (which means It will be watch only).
I'm not sure If it allow you to scan QR code (as the private key would be hard to re-type) , If it doesn't then just read the QR code (there is plenty of tools out there) and then copy and paste it .

Since the hardfork happened (as I can see on a few posts) , Is there is anything we should do in order to receive our ICNs ? like updating our wallets or redownloading the blockchain ? or continuing to use the current wallets (Ethereum wallet) is fine ?

Whether I'm trying to send a P.M , reply to a post/make a thread or simply visiting threads & sub sections page loading seem to be slow. I'm pretty sure It doesn't have anything to do with my internet as I'm browsing other website just fine. I'm the only one experiencing this or it's another DDOS attack ?
