hello
my C is a 240GB SSD
I installed the "Bitcoin Core" yesterday
it's been running about 30 hours and has taken up 42GB of space
I don't think I even have enough space for it to finish syncing up
why is it taking so much space ?
and why is it taking so long to sync up ?
gona be 40-50 hours

https://bitcoin.org/en/faq#what-does-synchronizing-mean-and-why-does-it-take-so-long

ive cleared another 10GB of space so it should be able to finish
can I assume it wont hold all the space it's taking on my C drive ?

I have an internet business that brings in about 4-5K a month
iv had bitpay sending all my BTC to my trader but now im trying to get into trading myself so I need my own BTC account
that's why I installed "Bitcoin Core" I knew it would take time to sync in but figured 5-6 hours not 2-3 days
and didn't expect it to fill up my C drive

once I got it installed I got the receiving address from it and put it in my bitpay which had 58EU in it waiting to be sent (today)
I got sic of waiting and setup "Bitcoin Core" on one of my servers and it is moving much faster there then at home
likely be synced up in 2-3 hours
but how do I transfer the BTC account from my home computer to my server ?
I see how to backup a wallet but not how to open one

My blocks and chainstate folders combined have ~65GB currently.


#1 Close core
#2 Put the wallet.dat in the correct place -> https://en.bitcoin.it/wiki/Data_directory#Default_Location
#3 start core

I have Bitcoind installed on my server and it's around 66GB.

You can enable pruning mode while syncing the blockchain.

To start pruning enter this on the command line -


where N is the size in MB that you want to allot for raw blocks. Minimum acceptable N is 550MB.

For now block pruning disables block relay and is incompatible with running a wallet due to the fact that block data is used for rescanning the wallet and importing keys or addresses. However these features will be included in version 0.12.

I've been running 0.12 with a 5GB pruned block chain, it's great if you don't have much space in that machine.

please explain this prune thing more
im unable to get it to work

Pruning is not done through the debug window, but rather the start up command. What you need to do is right click the shortcut to start Bitcoin Core and select properties. In the box that appears, add -prune=N to the end of the string in the box labeled "target". Make sure you have a space between what was already in that box and the prune option.

seems to be working
has cleared up 40GB

Didnt you want to run it as a wallet?

can use 0.12 beta to get wallet and pruning

Although its safer to use it, synchronizing and size are just reasons why i don't use bitcoin core.
I'm comfrtable using blockchain so far i don't store much anyway as i kept spending my btc every now and then.

I know, does OP know? Did they get 0.12 before just pruning away the information the wallet needs?

Full version is always better than the pruned version, IMO. 240GB should be able to last you quite a while.

what is the point of running core in pruned node without the wallet function, surely its not a full node then?

since you wanted your own bitcoin wallet and for business use,why dont you use a light weight wallet without all these hassle of downloading everything. i use electrum FYI

because my problem had drifted away from my topic here I made a new thread

turns out in pruned mode it CAN"T load a wallet
and when you disable Pruned mode it has to re download everything
also the new copy isn't actually out yet (in a few days im told)
and it would also need to do a full re download (yet more days)

I had a second copy running on my server that finished setting up today
I just aplied the data file to it and got it working correctly
nearly 2TB free on that drive so will never be an isu
the 240GB at home is not free it is the full size of my C drives SSD
and it was full cause of the BC core

anyway guy advised electrum
from what I understand it is not a standalone product
you need to have something else running on a server for it to connect to
I was told I can use the BC core that I have running on my server for that
also from what I understand most people have someone else running there real BC account and "electrum" just connects remotely
if I understand that correctly using a third party for this would mean your money isn't secure

I may have a few things wrong here since im just learning how the system works
but my plan is to run the BC core on one of my servers and run electrum on my home computer


Ps
thanks for all the help
im learning a lot in a hurry here

Can you wait for 0.12 and use a USB stick to start to build a pruned node. I'll probably try this on an old computer when it's available. It seemed like a good way to make a type of hardware wallet.

perhaps if your using public computers
im using only a private one so a usb still is not needed

Or you can use a lightweight bitcoin client. You can find some of them here: https://bitcoin.org/en/choose-your-wallet
