I have voted for $1200 and i think it is quite possible, price is getting some correction right now and i don't think this correction can brought price below $1200 level.

Looking at chart https://bitcoinwisdom.com/markets/bitstamp/btcusd
Price have touched 1230$ exactly but i think your orders were piled after another order at same price level. And there may not have been enough sells to execute your orders.

SebastianJu (https://bitcointalk.org/index.php?action=profile;u=18640) is quite well known escrow service provider and he is providing it for free (for tip if you want) and also pretty active. But you have to read about all of escrow service provider's terms and condition before using their escrow service.

Obviously there is no any such trading bot and even if you find some bot/service claiming to give you 10% profit daily its better to stay away from them. They will probably scam you, i have seen few working trading bots making 0.5% max per day and that is also not guaranteed profit. To use trading bots it require some skills and strategy so it is not a complete passive way to make profit.

Check coinb.in they are opensource web based bitcoin wallet but i don't think they have API option.
You have to run own bitcoin node (wallet) to create own api or you can simply call your node using jsonrpc.

Most of the bitcoin wallets have fee recommendation system which will tell you how much fee will be enough to get confirmation within next block.

But if you like to calculate manually http://bitcoin.stackexchange.com/questions/1195/how-to-calculate-transaction-size-before-sending
I think this is correct calculation.

Wow this is really cool update. I have watched video of amazon alexa several times and it is really useful and cool device. It will be easier to ask alexa from bed every morning "Alexa, ask BitcoinAverage for the bitcoin price" than searching for mobile on early morning and check price.

@BitcoinOffice are you real satoshi nakamoto  

I am suspecting this not only due to tone and the way OP is talking his local time is exactly same as of user admin https://bitcointalk.org/index.php?action=profile;u=1 and satoshi https://bitcointalk.org/index.php?action=profile;u=3

Either OP is real satoshi or some guy have just created account with time zone matching to satoshi.  

I can be completely wrong

You can add cubits.com and nicehash.com on the list, i have got email from both of them about cloudbleed this week. I have changed password in most of the site that have cloudflare.

You can buy bitcoin in face to face deal with some local guy who want to sell their bitcoin for hand cash, localbitcoins and paxful is best place to find them. Than store your bitcoin in cold wallet like paper or hardware wallet (don't store in web wallet that require personal details).

You can sell your bitcoin when you need through same process.

I have few transactions with 100 satoshi per byte fee stucked for more than hours.
Looks like half of this unconfirmed transaction are with 60-80 satoshi/byte fee. https://bitcoinfees.21.co/
So this may not be just low fee spam.

$2000 worth of bitcoin doesn't sound that big to cause any problem but i think you are trying to skip banking transaction. Purchasing bitcoin with hand cash is quite riskier but you can search for any local guy near you willing to sell bitcoin over localbitcoins or paxful and meet him face to face for deal.

0.10% is really high if you have to move large number of bitcoins daily and also there are limited places/merchants where bitgo is accepted. So you may end up paying more fees in bitcoin transaction just for sake of so called instant bitcoin transaction.

Also to have full control over your bitcoin, paper wallet and hardware wallet is perfect choice. You will be only one who will have access to a single private key of your bitcoin address so there will be no any risk about involvement of third party.

In past blockchain.info have feature to send out bitcoin with multiple bitcoin address to single bitcoin address in one transaction but it is not possible this days. But if you have all of this four addresses imported in blockchain.info wallet than you will have ability to send out bitcoin from one address to another.

Both A and B don't have enough bitcoin to send out 0.5BTC so It should be address C. If you send 0.5BTC from C to D you will have following input and output.

C 0.70BTC ---------> C 0.20BTC
                         D 0.50BTC

There is no doubt that localbitcoins is the first of its kind and paxful have popped up quite recently. That's why localbitcoins have more traders than paxful, i have also used both of them before. However i like localbitcoins because of lots of buy/sell offer with much more favorable terms for me.

You can try blockchain.info which allows you to sign and verify messages. For this you have to create a wallet there, generate bitcoin address from bitaddress.org in offline computer and import that address to your blockchain.info wallet. From than on you can sign messages whenever you want or you can use the private key of your bitcoin address to sign message using other services like coinb.in but entering your private key anywhere online is not recommended.

It is only in the chinese exchanger, in other trading platform bitcoin is actively being traded and price has already crossed $1000 and this time price growth looks healthy one rather than manipulated high pump/dump scheme we used to have before due to fake chinese trading volume.
