Thanks for your advice, mate. I own 2 SBC myself which are the Raspberry Pi 2 and 3, but still I would love to have an extra SBC to use as a full node for other cryptocurrency. Staking on these would be more secure, but I'd only prefer to stake 24/7 on a VPS due to internet unreliability.
In the meantime, I will encrypt my wallet from within the VPS for extra security and stake some coins myself. As it will be running 24/7, I think that I will have better chances of receiving stakes.
The ODROID-C2 single board computer looks pretty interesting too. It can be a great addition to my setup of nodes for cryptocurrencies.
