Closure of Group Buys

Due to underwhelming response for both the group buys, they will be closed with immediate effect.

For those who are looking to purchase USB Block Erupters from Bitfountain, you may indicate your interest by replying here.  I do have some on-hand that I can sell around SGD$50 each.

Alternatively, you can also get them cheap at bitcointalk.org forums but shipping may be costly (both in financial terms as well as waiting time).




KNCminer Venture [17 July 2013]

After paying KNCminer for the upgrade to Jupiter, below is our current balance.

SGD$ 97.56

KNCminer has updated the system to reflect the Jupiter upgrade!  Steady!  Let’s hope it comes early in October!

[Group Buy #1] Block Erupter USB Update – [CLOSED]

[9 Sep 2013]  This group buy is no longer available.

Please see below for the updated interest.  Kindly review your status and email me the details marked as “NO”.

Qty Name Email Address Mobile No.

Don’t forget we need at least 50 qty to be able to close the group buy.  If you do have interest to purchase, do drop me an email at derekleong75@gmail.com

Unlike other group buys at bitcointalk.org where BTC are collected to secure a spot (as well as to lock your BTC in), ours just need a commit from your end.  BTC will only be collected when the group buy is 90% full.  So don’t feel obligated to commit.

Since it’s only open for MY/SG, it really needs a lot of support from folks to meet the requirements.


Please understand bitcoin mining difficulty and ROI on these devices.  bengx has a good chart to estimate ROI which can be found here.
