Well I'm unlikely to test it with anything of actual worth am I But essentially the mechanism of deposit and withdrawal worked for this altcoin.
I did notice one couldn't buy or sell (Markets Paused).

Alt coin worked (in this case) the test was LEAF

No idea if other currencies would work, but something did. I transferred that to coinmarket earlier today and back again to cryptsy.

Hmm fair points.

A decentralized exchange that runs off of the back of the very coin(s) that's mined, self sustaining etc.

*thinks* is that even possible? I need to give this some thought.

fwiw I've initiated a transfer with coinmarket.io to see if it works. Very low amount of alts.

To be fair their FAQ says:

"Are you going to run off with my coins?"

"Yes, we are planning to shut down and buy our private island -
as soon as enough people deposit their hard earned coins."

So ya know, devils in the detail n all that.

Meanwhile, and just on the offchance that people aren't guilty of mass fraud should personal details be posted here?
Is the forum permitting such things?

The 270x settings I posted here may perform just as well on the 270. Donno, give it a crack.

Here's a longer sample:

--------------------------------------------------------------------------------

Here's my config file. It's an HD7770 with a gig of ram. cgminer version 3.7.2 on Windows7 64bit. 8Gig of ram and a bulldozer 6 core.

color 17
setx GPU_MAX_ALLOC_PERCENT 100
setx GPUUSESYNCOBJECTS=1
cgminer.exe --scrypt -u username -p password-o stratum+tcp://coinotron.com:3337 --gpu-platform 0 -d 0 -g 1 -w 512 -I 17 --thread-concurrency 8000

This runs at 195Kh/s with a WU of between 170-180. I've tried various worker sizes and clocks and intensities, but these settings appear to be the best for me. I get zero HW errors and 99.5%+ accepted.

Clocks set at 0.71 ratio of: Core - 965Mhz Memory - 1360Mhz

I set the fan to run at 100% as this runs pretty warm hovering around 83C to 85C though I could probably improve airflow in the PC as I've a side mounted fan not in use at present. This is using the latest CCC
