It's not about the cost of the coin, it's about the cost relative to how many coins exist and if they have a viable business model that will sustainably separate them from the pack. ETH has this to the degree that they aren't destroyed by their own success with the ICOs that are pumping and dumping their price all over the place. Sia has it to the extent that the business concept is good, but sustained execution and growth is still to be seen. With Stratis, MS coding language use is not a long term sustainable advantage. It's a niche that's unique at the moment and that's it.
