StakeandNodes, I think some of the coins on your list are there unfairly. I don't know about all of them, but a couple that I am part of, DixiCoin and Nihilo don't deserve to be on your list. Both are very advanced in their development of the platforms they are releasing and have provided the community screenshots and Nihilo is releasing regular weekly updates of their development. If you looked at their latest update you will see they are not just another masternode.
I also wonder what your process is for updating your list. Are you reviewing each coin weekly? Monthly? At all? If not, your list will become out of date very quickly and could be unfairly damaging to some projects.
You have created this list, which I believe to be inaccurate already. You need to responsibly and actively manage it, or you should take it down.
My list will be evolving as I continue to review coins and monitor their activity and production. As you see at the bottom of the list it has a date and has yet to be a week since it was released.
DixiCoin - At the time of review DixiCoin was 30 days from Genesis block. Please understand that in the masternode space exit scams are common within the first 60 days despite any promises made.
Nihilo - Roadmap shows nothing utility wise being delivered until Q2 2019. The marketplace is not due until Q3 2019 which is their main utility. It is also less than 50 days since genesis block.
One dev of a coin reached out and after being show additional information that wasnt readily available I removed them off the list. Ideally this list would be empty.
I think your method of analysis is flawed. It is very shallow and is not comprehensive enough to be categorising coins as JAM.
Many coins deliver well in advance of the timelines on their roadmap. For example, Nihilo's marketplace will be delivered at the end of April to early May this year. There is a lot more going on there which you would see if you read their weekly update. By failing to read this type of information being released by projects is why your "analysis" is flawed.
The only reason you can do it is because this is crypto. If this was shares your "analysis" would be considered a joke. If you take yourself seriously, you should to your analysis properly and show your analysis.
