When you send transaction in BTC, all content of one or more of your adresses are taken and used and part of it will be send to you into your new address, that is probably hidden from you in client.
Example: you have: 1address1 1BTC 1address2 1BTC
and want to send 1.5BTC to 1adresss3
It will get all these: 1address1 1BTC 1address2 1BTC and sends them this way: 1address3 1.5BTC 1address4 0.5BTC
Where 1address4 is your address that client generated for you.
Hi, I'm thinking of building a GPU rig for LTC mining. Can I ask you a few guestions?
1) Does LTC mining require (benefit from) good CPU, or I can use the cheapest single-core available?
2) Does mining benefit from more system RAM? Is there some minumum per rig or per card or other recommended metric?
3) Is it required to insert GPU for LTC mining into pci-e x16, or it works without loss in slower ports like x4 / x2? (~Does mining use a lot of bandwidth?)
4) I see motherboards with up to 7 pci-e slots in shop. But mining rigs usually have 3 or 4 cards. Why is that? Because of best hashrate/money ratio? Or motherboard/system can't handle that much top-grafic cards at once? Because of heat control or PSU limits?
5) Internet connection minimum requirements. Is there any recommended minimum on speed/latency? For example if I use GSM to connect miner etc...
6) Is there any good complete guideline for setting up a rig (not just hundreds of posts in forum)?
