Thank you very much
When I activate the limit and it is set to 2 GB, it seems that 12 GB will be saved. Not 600. It is true?
But still, I don't understand that I don't have 600 gigs of space, where is the downloaded 600 gigs saved! UPDATE: I realized. The blockchain will be downloaded and removed from the hard drive at the same time, and the amount of 12 gigs will remain.
And one more question. Does the pruned node do the same thing that full does? I want to know if what I am doing is valuable or not.
When you run a pruned node, the node is downloading each block and after it verifies the transactions in a block, it discards the block and keeps only the unspent transaction outputs on the disk. That's how it's able to keep the disk space really small. So you can't use the Bitcoin CLI to fetch blocks. Otherwise a pruned node can do everything else a full node can.
