Transaction fees are scary 0.o

For reference: I'm using Preev and BTC-e for my bitcoin pricing.  I'm using bitcoin core 0.14.1 as a client.

Maybe I'm doing something wrong. I went to the gas station and bought $50 worth of bitcoins. I want to send $30 worth of these coins to BTC-e for a single Litecoin purchase, just to get back on my feet, it's been a while.  I'll buy more btc to stay as btc later, but for now I really want my hands on one ltc and to keep it there on the exchange.

The fee proposed by bitcoin core is 25 blocks (0.00265823) approximately $5 at this time. For a 20 minute transaction, it asks 2 blocks for 0.00424066 (approx $10).

So, for my attempt to send 0.01155 BTC ($30) to the exchange, and using the custom fee area in the bitcoin core client, how much would YOU attempt to put where it says per kilobyte, hoping for a 1-3 hour transaction?  Worst case, 7 hour, how much would you enter into the field?

In the Bitcoin Core wallet, receive tab, I made a payment address with a fixed amount (for a purchase button).

Edit: I figured it out... For some reason I thought it included some complex process like the paypal button... nothing of the sort!

All I did was click copy URI, pasted it in the button using the following format (here for reference for anyone who needs it)

on(release) {
getURL("bitcoin:abcdefg123?amount=0.07&label=Panda%20Canvas&message=Purchase%20Panda%20Canvas");
}

Edit:  Forget it, delete this topic if you wish.  I was mining the WRONG pandacoin  xD  (did the pre-mine version).  Real one uses CGminer and not pre-mined.  Up and running at full speed.  Whew..







New to the verti-scene so I hope someone can review my setup. I know mining PND is a bit different (seems to work better with lower intensity and worksize).  Please see if you can correct my setup to get max performance (unattended machine).  I know I did this wrong, so please help me tweak this

GPU = ASUS 5870v2

vertminer --scrypt-vert -o stratum+tcp://panda.united-miners.com:3311 -u name.name -p x --thread-concurrency 8000 --intensity 13 --worksize 64 -g 1

Windows 7 64bit  CPU mining.
Cointron LTC mining

I've been using minerd.exe and mining_proxy.exe with the following commands on my main system and it works with no problem:

c:\ltcminer\mining_proxy -pa scrypt -o coinotron.com -p 3334
c:\ltcminer\minerd -a scrypt -r 1 -t 2 -s 6 -o http://127.0.0.1:8332 -O (my user name).1:1
(my user name - what i registered with but not shown).

I've recently diverted work to the laptops and freed up the main system for BTC mining.  On my laptops I'm not always getting the results I want. (using different workers btw)

For the first couple of times it shows the following: accepted 1/1 (100%) <yay!!!>   then  2/2; 3/3 up till about 4/4.  At that point, it starts showing this:  JSON-RPC call failed: {"message": "Unexpected error during authorization", "code": -1   json_rpc_call failed , retry after 30 seconds

After that, it begins to hash again and shows LONGPOLL detected new block, but the <yay!!!> have stopped appearing and the cointron dashboard shows the work has stopped  (0kh/s).

What do you suppose causes this?  Tried looking around, those who had similar issues were using 3333 port instead of 3334, but I'm definitely using 3334, plus I was getting working results for the first couple of runs, then it craps out and the work comes to a halt.

On Windows 8, guiminer reports "Verification Failed: Check Hardware".  Tried all Catalyst versions from 12.6 to 13.3

On Windows 7 (dual booted) it works flawlessly on any driver version, even 13.3b.  Mines nonstop without any trouble.

Why is this happening?  It's not defective hardware, checked that already. I'm reading it might be SDK related, but how can I troubleshoot that?  I uninstalled all ATI software, reinstalled 13.3b and no go.. Do I have to install OpenCL or SDK or anything "separate" from the actual catalyst driver? (direct links would be helpful).  Thanks pals.  Hope to get this resolved once and for all

also note, some catalyst versions under win8 were causing guiminer to not launch at all.  (not the same as the "hiding" issue)  it simply would not execute.  13.3b it does execute, but gets the check hardware message.

I'm planning  page where I want to sell shirts n goodies for bitcoins. I'm not certain how it will work out.  If I list an item for a set amount of bitcoins using merchant tools from mt gox or other, will that price automatically change to equal the "current value of other currencies such as USD"?  Or will I have to manually change the price?

secondary question if applicable,  are there any "flash action script" based bitcoin buy it now buttons?  i've never sold anything in bitcoin, but looking forward to it and in flash if possible   currently no tutorials appear on the good so hope someone here knows something.

It's been a while since I mined, heck I still have 1.0 bitcoin still in my account (didn't request a payout). Just started up again 2 days ago. All was well until today when I got the following error (it occured earlier, but this is the 2nd time):

btcguild.com:8332 09/04/2013 16:24:11, 'NoneType' object has no attribute 'settimeout'.

It clears up when I start mining again, but eventually does it again after a few hours.  I also noticed that it says something like "job finished, idle" a couple of times and then that goes away.. not sure if that affects my mining too.

I use Guiminer (latest) with BTC Guild.

On a side note, I read recently that I need to start using stratum1.btcguild.com:3333,  not exactly sure how to configure that in guiminer. I looked at the "servers.ini" and it's not clear where to make the changes...

            "balance_host": "www.btcguild.com",
            "balance_token_url": "http://www.btcguild.com/my_api.php",
            "balance_url": "/api.php?api_key=%s",
            "host": "btcguild.com",
            "name": "BTC Guild (any)",
            "port": 8332,
            "url": "http://www.btcguild.com"

Could someone append this for me?   Or am I supposed to use a different miner?
