How open port ?

What does than mean exactly? Other software wallets can't be kept as cold storage? It is only Bitcoin Core property?

how do i open port 8333 is it settings>options>network --conect through socks5 port?

I'm not sure what you're trying to tell us here. Why would you use 0.9.6? Seems like a slightly eccentric choice for your test client. As a miner. I would have expected you to understand the relevance of the client version in a performance test.

And what does "1.9GHz Dell" and "3.1 Ghz Intel" actually tell us? Not all clock cycles are created equally 

in this situation, it's more safe to use a refurbished laptop PC with an i5 processor (like i5-560 ...).
200 USD for this setup on amazon.

I dont plan on ever using the wallet anyway, so am i right in saying this shouldnt be a problem?

was abit cautious about this post also so i ignored it.  op is probably genuine but prob best to avoid unless you completely know what you are doing.

Bootstrap.dat gets it to about 20-ish GB of 40-something GB, so it does not get you out of a couple of days of heavy -reindex processing
I've recently been testing a variety of smaller and older PC's with bitcoin-qt client wallet and full blockchain on linux.

Pro:
You have your own copy of the whole blockchain since 2009
You can add things such as your own electrum pruned blockchain server so that you know whose node your fast wallet get its data from (and so that you can hide it up a branchline in your extensive LAN where most criminals wouldn't find it)
By choosing what sort of node it is you put in a 'vote' on the xt block size question

Con:
It needs > 50GB of HDD (Dec 2015) and will need even more next year
The overheads of running your pc 24h might be 1kWh per day electricity plus minor increased wear and tear on moving parts and storage devices.


Here is a list of (mostly failed) combinations:
bitcoin-qt 0.9.6
512MB single core 1.6GHz AMD - forget it
1024MB quad core 1GHz raspberry pi - forget it.  burned out a 64GB usb stick with too many rw before it had reindexed the blockchain
2048MB duel core 1.9GHz Dell - OK
6.2GB quad core 3.1 GHz Intel - OK, except that 0.9.6 is now obselete

bitcoin-qt 0.11.0
6.2GB quad core 3.1 GHz Intel - presently reindexing the blockchain (since 25th November)

If you don't want to know where Electrum gets its blockchain info from, then it might suit you better than running a full node.

Yes, please do it. We need more individuals to store the blockchain. I did with the latest desktop I've bought. Note that it's smart to have 2 computers though, if you want to do P2P or download software which doesn't come from a trustworthy source.

It's probably too old bootstrap.dat file. 27 GB only???

I would urge anyone thinking about doing this to think twice. The bootstrap.dat linked from the website could actually be some kind of attack, although I don't know exactly how the file gets used so I can't tell you what the vector might be.

Anyway, since 0.10, the bootstrap.dat method is basically obsolete. It is not faster than downloading directly over the Bitcoin network, so it serves no purpose.

pro :
- emit your own transactions
- can keep wallet file as cold storage (keep my money safe)

con :
- need actually 55Go to store
- need 2-4ko/s of Upload
- need to trust the "PC" ... system operator

On my main desktop I have bitcoin core and support the network.
On my laptop I use electrum for fast transactions and easy
sync. So I suggest using both as long as core wont bog down
your computer. Assuming you have a good comp since its new.

You can speed up the bitcoin core sync time by downloading the whole blockchain in a bootstrap.dat file, then letting your bitcoin wallet work on that. It still takes a long time to sync but it's faster than waiting for the data from nodes. You can download the bootstrap.dat file from this link.

Thanks everyone for the replies, i think ill give it ago, i have a new i7 with 3TB of unused hd, and my broadband is unlimited..... so i can try it out and see. 

im not even looking to use the wallet anyway as i have all my bitcoin in paper wallets.  so that isnt an issue.  bitnodes sounds interesting i might look into that.


 

Thank for explaining in brief.
I was thing of the same but one person in above comment said that It would take weeks to get fraction of bitcoin, so I thought to ask here.
Thank you guys.

Advantage: help to support the network. Which is a kind of "altruistic" advantage

Disadvantage: time consuming, space not used for other things, harder work on your hd (which lowers its life span), slowing your machine on the operation...

Even those pools won't reward a lot if compared to what these big farms have been making...
You will need to invest a lot if you want to earn bitcoins through mining...

^Can't you link the posts altogether?

Bitcoin Core is essential for the survivial of Bitcoin, full nodes basically forms the backbone of Bitcoin. There is no reward scheme in the protocol which rewards the node. However, the number of nodes is decreasing. Hence, Bitnodes have a program which runs for a limited time and basically rewards nodes randomly. You can find out more information here: https://bitnodes.21.co/nodes/incentive/. Currently, the possible reward for the winner is $10. You need to have a "PIX" score of more than 8 to qualify. Here is the algorithm for calculating it: https://bitnodes.21.co/nodes/leaderboard/, just scroll down. By running a full node with port 8333 opened, peers will connect to you and download blocks from you. It will result in a higher bandwidth usage.

I'm thinking of running a full node on a dedicated server. It costs a lot but it helps the network.

Edit: Some punctuation and grammar errors corrected.

No right now you will not get rewarded by supporting via a node.
You only get rewarded if you mine.And today the difficulty is that high that as a home miner you have no chance to compete against the big farms.The only thing you can do is joining a pool.
