interested how many coins do I need to run a node?
You need 1000 GBX
Which hardware requirements for running Gobyte masternode, dev?
To compile the wallet on a Linux you will need at least 2GB or have a page file up to 2GB.
The Masternode itself can be hosted on a Raspberry Pi.
Can I run it on Windows 10, Dev? (Masternode)
Yes, you can but you have to know that your MN has to be 24/7 up. The ports have to be managed correctly and no restarts for windows updates.
So Linux would be an easier way to manage it.
