Greetings to all good will people! Now, when the bunch of deceitful, greedy, incompetent, irresponsible idiots from B2X (sorry for some harshness) are really endangering the Bitcoin, All of us who are smart enough and responsible should immediately start a Bitcoin core (best of all the latest 0.15.0.1 version) full node client! If until now you haven't started your own bitcoin core client - just do it right now! Believe me it is so simple! Personally I have been running mine for 3 months already. For those of you who perchance are afraid of keeping money in a wallet which is constantly connected to the Internet, and even accepting incoming connections (be sure to turn this option on), I want to say that you do absolutely not need to store any money in your Core full node client! You may just keep somewhere offline just a key phrase for recovering your bitcoin private keys and addresses (your real wallet). Or you may run somewhere on another computer the electrum wallet, or any other wallet that allows you, and no one else, have full control over your wallet's private keys. In my own full node bitcoin core 0.15.0.1 client, for example, I keep absolutely no bitcoins at all. I run it solely for supporting the true bitcoin network! The most important thing is that your Bitcoin Core full node should be ONLINE as much as possible! (After you setup your Core full node do obligatorily check that you really have the 8333 port open and accessible from outside. You may check if your node is seen from outside here for example : https://bitnodes.21.co Yes I think it is very important now as the majority of the hash power will be switched to the 2x chain. We need to show support for the core and our true bitcoin, we cannot be threatened by the miners to turn off the power from the main chain. If we will ignore 2x they will just come back to the real bitcoin, people should panic, we don't need that 80% of power. The difficulty will be adjusted after some time and everything will go back to normal.

Of course! The TRUE Bitcoin is the only REAL, TRUE money! And if you control your private keys it IS indeed your only REAL money!! And your real FREEDOM in this (to a very large extent) material would! So I'm absolutely sure that running Bitcoin Core Full node, donating those 200 Gb free hdd space and some other tiny hardware donations - all that is just nothing compared to the Bitcoin's true value and prospects!!

As for the speed, my home internet connection is very fast now but the blockchain downloading (syncing) was VERY slow. My download bandwidth was being used at 2-3% only.
Core downloads blocks from many sources and it is comparable to a torrent. The downloading itself is fast but the validation process is very slow. Its not a problem with the internet speed but rather, your hardware speed. But if there is a security risk, then maybe is there a Bitcoin Core command or something to validate all its database against the actual real blockchain?
There really isn't a security risk. The security risk it has would be the same as a user downloading any other files from the internet. If you want to be extra safe, use -reindex when you start Bitcoin Core up. Be warned that it could take days for it to be completed. the chain that will be chosen as the dominatn one is that with the most nodes running up. So if you support Bitcoin Core you must run a Bitcoin Core node and accept and check transactions with it.
good luck
No. Nothing is chosen in the hardfork. Both chain will still exist. If you want to help other to download the whole blockchain just make sure your node accepts incoming connections.
No. Outgoing connections also helps others to synchronize their blockchain.

Its not a problem with the internet speed but rather, your hardware speed. It seems to me, you are not quite right here. When my Bitcoin Core 0.14.2 was syncing itself (downloading the blockchain), I saw the bottleneck was precisely in an insufficient number of other full nodes that accepted incoming connections, from where my node could download the blockchain data. As memory, processor, Internet channel, all they were busy for only 2-6%! You compared to torrents. OK, when I started any popular torrent on the very same computer, then the whole my 2.5-3Mb/s download bandwidth was immediately busy at 100% (ram and cpu were of course still almost free). But if I started a rare unpopular torrent then it would be similar to syncing the blockchain as of June this year - very slow indeed

There is also another potential factor that you ignored. If your internet connection is somehow throttled, it would definitely be much slower. In addition, if your internet is slow, that can be a bottleneck. Bitcoin Core is also heavily reliant on the disk speed. If your read/write speeds are slow, it would also be a bottleneck. I wouldn't pin the problem straight to the lack of nodes. You have 8 outgoing connections and the blocks are all supplied to you, if you have less than that, you can add nodes manually. I have never encountered a problem with the synchronization due to the lack of nodes, it has always been on my computers. You compared to torrents. OK, when I started any popular torrent on the very same computer, then the whole my 2.5-3Mb/s download bandwidth was immediately busy at 100% (ram and cpu were of course still almost free). But if I started a rare unpopular torrent then it would be similar to syncing the blockchain as of June this year - very slow indeed
Of course. Torrent doesn't have validations that is on the level of Bitcoin Core. It would naturally be way faster. The only reason why the synchronization would be a lot slower is due to the fact that there are more transactions in the blocks that Core have to validate. I'm completely with running a full node to support the network. But the average joe, doesn't have to.

No, no, my internet has been neither throttled, nor slow. The only potentially possible bottleneck related to my computer could have been hard disk read/write operations (as it was a usual 7200 rpm hdd, not an SSD). But! At a moment (when the downloaded blockchain data had not exceeded 32Gb) I tried to move the data directories to a fast USB 3.0 flash card (exactly to find what was the bottleneck). The syncing did become a little bit faster indeed. But Not significantly!

I've been running a full node over public WiFi since I joined Bitcoin Talk, and I've had very few problems apart from the initial download of the blockchain. In fact, that was taking so long that I used a cable connection to complete the synchronisation. I'm running the node on a Windows 10 notebook, and Idecided to run a second node on a small netbook. I bought an SSD, and copied the blockchain onto that ( I used the notebook as source of course). Ubuntu picked that up without any trouble. I ran the two nodes for a couple of months with no difficulty. but Idecided that the Linux node was a bit of an abuse of the hospitality provided by my WiFi donors, so I deleted the blockchain on the SSD. I can't accept inbound connections, but the full and unpruned node seems to be stable and up to date without this.
I'm still considering how to handle the recent forks, and I may start a forked node on the netbook to pick up a few altcoins to convert into Bitcoin.

I also download the blockchain in my best CPU and then copy the data to my other devices where I have nodes (rPi, Pine64, etc) It works like a charm. I dont think you could get alts if you start a node from a fork. I think you better stay with the bitcoin core node and support the network.

I see Bitcoin as a store of wealth, and I support core. However, I'm not averse to increasing my savings by collecting a few free coins, and converting them in the true Bitcoin.

OK, but remember the 2x attack on the true Bitcoin is too serious a danger to be 'collecting a few free coins' at the very time of the attack! Therefore, in pursuit of an additional tiny profit, you are going to seriously risk losing your main true wealth on the contrary

How will running a Bitcoin cash node (for example) on a second machine whilst I cellect some free money affect Bitcoin? If I keep my core node running on my primary machine, then it seems to be to the advantage of Bitcoin, as it will just increase the value of Bitcoin. A much bigger threat would be for me to sell my Bitcoin and save the money in a fiat bank account. This is something that a lot of Bitcoin Talk members seem to do.

I'd like not to argue on 2x here any more, I'll just say there's a big difference between the cash fork and 2x fork: the cash fork was honestly openly implemented as an altcoin with a reliable replay protection, whilst there's a crude, blatant attempt to force their own (unnecessary after the Segwit activation!) 2Mb blocks hard fork without implementing any replay protection at all! I fully agree with you in your other statement that escaping into fiats seems to be not very wise (and pretty cowardly)

The syncing did become a little bit faster indeed. But Not significantly! I run Bitcoin Core on a VPS with high-speed internet and SSD disks. The bottleneck during initial block download for me is definitely CPU (100% CPU utilization). I've noticed the same thing on my desktop system. So it really depends on your hardware and your internet connection.

ScripterRon, definitely, in my case CPU has never been the case: peak cpu loads % never exceeded about 10-12%, the average load was usually significantly slower at all

Hmm, weird. Given that it was the earlier blocks, synchronization should have been pretty fast. If the synchronzation did become faster after you switch, it would mean that the node's speed wasn't the main bottleneck. What are your system's specs? A solution that I use is to increase the dbcache. If you increase the dbcache, the synchronization would be exponentially faster. You do need a good amount of ram though.

Wierd, of course! Very good that you've noticed! I've been so much busy writing in many threads at this forum simultaneously these days, that I made an annoying, stupid mistake! I tried the flash drive when the already downloaded blockchain had not exceeded (but was already close to) 128Gb - that is really the size of my largest, fast (at that moment free) USB flash drive (it is ADATA UE700 128Gb).

Even though there's no monetary reward for running a full bitcoin node, I still feel like I want to run one myself at some point. Right now now I have one main machine for all my needs but as soon as I get a new one I will dedicate at least one to cryptocurrency. And I will be running a full node on that machine. I hope more and more people start doing this as well even though there's no monetary reward.

This is actually new to me about running full node on a computer just to support the Bitcoin community. For what? What are the benefits of running 24/7 that costs power but what in return? I guess big mining companies are doing the same way since they have top of the line hardware. I wish one day I could get my hands on the work to experience this Bitcoin core personally.

Supporting the TRUE Bitcoin network, its most reliable, really competent developers team and its main and most important application Bitcoin Core wallet.
Supporting them, along with realizing the extreme importance of 'the more, the better' number of full Bitcoin nodes for implementing the true decentralized, free, REAL money world service (especially taking into account the 2x threat) - these are exclusively serious, necessary and sufficient reasons to as soon as possible start your own Bitcoin Core 0.15 full node.
Now for the 'cost'. I wrote this (when people worried about their costs, benefits, etc. in running full nodes) : In my opinion, the biggest monetization is the maintenance of the TRUE Bitcoin blockchain itself, the prospect and the gradual growth of Bitcoin's exchange rate is going to fully compensate you all of your costs.
Personally, my bitcoin core full node costs me almost nothing: the node is launched on my laptop that I set up to be always online (banned hibernation, sleep, automatic restarts after updates, all done through group policies).
It consumes very little energy, my home Internet channel is unlimited.
I disabled torrents, etc., to provide the entire upload bandwidth exclusively to my Bitcoin Core 0.15.0.1 uploads.
And this: The TRUE Bitcoin is the only REAL, TRUE money! And if you control your private keys it IS indeed your only REAL money!! And your real FREEDOM in this (to a very large extent) material would!
So I'm absolutely sure that running Bitcoin Core Full node, donating those 200 Gb free hdd space and some other tiny hardware donations - all that is just nothing compared to the Bitcoin's true value and prospects!!
