Most of the trades below 1.0 will be far less interesting due to validation, it needs 0.1 (10%!) to get validated in a less-than-year time, for small transaction it's not interesting.

Even ripple which is meant to be able to easily do small trades, usually gateways will refuse trades which are too small, sadly.

and it produces like 0.6 LTC per day (with a pool), which last week was like $4/LTC which means $1.4 pure benefit per day... just a little something

I use an APC Back-UPS to know how much my PC eats power, with a full mining Litecoin(not bitcoin) GPU with ATI 5870, I'm at 350kH/s with cgminer (not bitcoin with Mh/s) and it says I eat up 320W and it seems to cost like €0.75 per day.

They are being flooded by too many new accounts, the waiting line to be validated is like 15000 when you create the account, and it really takes nearly 2 weeks to get validated...
They can have many new accounts (just to give an eye) but only a part of them will really trade on the market, and they're delayed due to the validation process...

I once read a paper on Advogato trust metrics and I think this could be useful as a complement in order to help identify people of trust in the ripple network.

This can especially help in the case a new gateway appears !
Or someone offering service like a gateway but not enough reputation to start up

what do you think ?

I have been mining LTC for some weeks, and I think it has better protection against massive generation like asics or multiple gpus, do you think it's better to mine btc with a pool or ltc ?

Thanks
