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 forums but shipping may be costly (both in financial terms as well as waiting time).




[Group Buy #2] 0.5 BTC Casascius Coins [CLOSED]

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

Hi Guys,

Thank you for dropping by to view the proposal for the second group buy I am running for 0.5 Casascius Physical Bitcoins.

These coins are nice collectibles and also have BTC value protected in them.

Same rules as per Group Buy #1, only available for SG/MY Bitcoin enthusiasts only.

If this group buy succeeds, I will start another for the 1 BTC Physical Coins.  So mine/trade hard for more BTC to spend in future!


[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

Unlike other group buys at 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.
