2  Economy / Currency exchange / Buy BTC with PayPal on: September 29, 2014, 12:32:40 PM
Hi, I know it is very risky to sell bitcoins with paypal, but I don't have any other options for now

If you will to sell me BTC just let me know, I will find another way to buy BTC other than paypal, but in the meantime I can only pay with Paypal
Currently I need around 1 BTC per day, bitstamp rate is okay

So, just PM me and let me know

3  Alternate cryptocurrencies / Mining (Altcoins) / Native Burst miner [OSX] [Win] [Linux] on: September 21, 2014, 12:31:00 PM
download binary here
source code is here
website is here

to configure, just edit mining.conf file in packaged bin, app will automatically look for this file when run, unless you specify costom .conf file

this is for burst pool v2 mining only
miner will use 2x staggerSize x 64 byte per plot file

  • it use C++ and native compiled, should be faster and less memory consumption compared to java miner
  • binary available for osx, win64 and linux64 (on linux most of the case you still need to recompile it, to do this clone source from github and issue "make" command
  • multithreaded miner, it will keep reading without pause when submiting share
  • added random delay when submitting nonce, to ensure you dont submitting nonce during peak submission on pool
  • it will auto retry if nonce submission is failed
  • multi account, multi-plots, just configure path to plot or directory inside mining.conf, it will autmatically search for valid plot file, dont worry if have another file inside plot directory, it wont read it

6  Bitcoin / Development & Technical Discussion / bitcoin maximum fraction unit? there are something less than satoshi unit? on: March 27, 2014, 05:18:31 PM
based on transaction structure

The TxOut structure consists of the following fields:
Field Size Description Data type Comments
8         value            int64_t Transaction Value
1+         pk_script length var_int Length of the pk_script
 ?         pk_script        uchar[] Usually contains the public key as a Bitcoin script setting up conditions to claim this output

so maximum transaction value is signed? 64-bit integer ?
why we use signed int? can transaction value be negative?


if its uin64_t so then max value would be
2^64-1 = 18,446,744,073,709,551,615

there are max 21 million cap of bitcoin so
so we can add 3 more digits after satoshi unit?

if its int64_t then max value would be
2^63-1 = 9,223,372,036,854,775,807

still more 3 digits after satoshi unit?
7  Bitcoin / Development & Technical Discussion / how to test if my hash is valid for a stratum pool on: March 23, 2014, 10:10:07 PM
i am creating cpu bitcoin miner (with stratum) just for learning

i can test my sha256d function are correct by compared input and output to other well known function,
but my concern is, how to make sure that my share to pool is correct as pool requested (byte order, json format, etc..), currently i tested it on pool, with minimal difficulty is 16, still i can't found a share since i am mining with cpu, is there a pool with minimal difficulty is 1 so i can test if pool can accept or reject my hash?

or is there any other scheme where i can test against ?
8  Bitcoin / Mining speculation / R9 280X for US $311 ? on: December 31, 2013, 08:29:50 PM
this is local PC store in Indonesia, you will notice that these items are cheaper than market

Power Color Radeon R9 280X 3GB      Rp 3,791,000 = 310$

ref :

i don't know if they made a mistake, but they said it was true, should i buy them? do you want group buy it?
9  Bitcoin / Mining software (miners) / CryptoSlax Linux Mining Distro on: December 29, 2013, 12:16:45 AM
hi, i just modified slax linux distro specifically for gpu and cpu mining, i prefer slax because you can run it without any storage device (harddisk or flashdisk) since it can copy itself entirely to run from PC memory, which is cool !

build 0.3-beta2 update 0.3 final are ready, go to

CryptoSLAX 0.3, download (316 MB) or on official website :

Features :
  • only need minimal 512 MB USB FlashDisk
  • can run with unplugged flash disk, since SLAX can copy itself to run from computer RAM
  • built-in cgMiner-3.7.2 with support for GPU scrypt (ltc, doge & friends), scrypt:2048 (vertcoin), SHA256 (bitcoin), keccak(sha3:maxcoin)
  • built-in yvg1900 protoshares cpu miner (all 64-bit variation of CPU)
  • built-in jhPrimeMiner xpm cpu miner (all 64-bit variation of CPU)
  • built-in clPts 0.2.2 (protoshare opencl miner)
  • built-in vertcoin cpu miner from
  • built-in cgminer bitcoin miner (asic) 3.12.3
  • built-in vnc-server, sshd, smbd (automatically run out-of-the-box)
  • built-in AMD Catalyst 13.12 with ADL SDK 6.0 and AMD APP SDK 2.9
  • minimal installation, only KDE desktop with text-editor, web-browser, and file-manager

How To Install :
  • 1. Extract the content of .7z to formatted flash disk with FAT32 Partition
  • 2. Run [FLASHDISK]\slax\boot\bootinst.bat (on linux run
  • 3. Boot from it (make sure persistence changes is checked for first boot)
  • *. if needed, root password is toor

Changes :
  • updated AMD Catalyst to 13.12 , APP SDK 2.9, and AMD ADL 6.0
  • custom re-compiled x86_64 kernel to support AMD IOMMU
  • automatically detect AMD GPUs on first boot, and set
  • auto run VNC-server for display 0 on port 5901 on KDE login (warning : no-password!)
  • auto run SMB-server on boot (warning : no-password! , root access!)
  • auto sync local time with ntp server on boot
  • fully working KDE desktop, now dbus is working (you can copy-paste now, lol!)
  • clean-up using .sb, rootcopy folder now only has miner config files
  • now i call it CryptoSlax since slax-cryptominer is too long
  • added KDE mainmenu items to launch miner or edit miner config files
  • on launching miner, it will create screen session before run the miner, so you can access it from ssh remotely

warning : this distro is not secure, there are no firewall, and most service are open for root access without password
note: this is beta version, please report any kind of bugs or feature request
10  Bitcoin / Mining software (miners) / mining pool proxy on: December 28, 2013, 04:27:21 PM
i run more than 6 computers for mining, all of them directed to same mining pool, in the case where i need to switch pool, i need to switch them one by one, is there any proxy for mining that i can use, so that i just need to direct all my cgminers to that proxy, and when i need to switch pool, i just need to set it at the proxy once for all miners.
