At least one node to run for SONM is in my plans as well. I short little numbers of tokens to reach the required quantity. That I will manage to pick somehow in short time over the next days. FOG computing is future and SONM team with vision and well planning is keep advancing that is great and notable while others are busy in getting short profits.
For a block producing masternode, you need like 500,000 SNM. At today's prices - that's like $100,000. Better buy more SNM tokens now while it is still cheap.
The gate nodes still give a great ROI, estimated around 10-15% a year, in the future even 20% when the network is used a lot. Imagine earning 20K Sonm a year when the value is at a couple dollars a coin.
