Full node of bitcoin I would like to have Bitcoin Core running as a full node. I thought it is like plus 100 GB. But on the web site it says it is no more than 20 GB. When I run Bitcoin-Qt is it enough to run full node or do I add any parameters before I start the program ?
You may run bitcoin-qt the very first time just executing bitcoin-qt.exe (I assume you are windows user) and make changes later

Yes, there are some useful options. For example, I do not like that this program creates database on my disk [C:] under the \users\user...\folder

I like to keep my bitcoin database in D:\bitcoin

So, I have created file bitcoin.bat with the following contents:



start bitcoin-qt.exe -datadir=d:\bitcoin




There are other options, but I think that you will find them yourself later. Default options are quite good.
