bad project
Yes this is definitely bad project for you. Based on the entry in your trust summary you would rather choose and promote ponzi shame.
"multyple user" - yhy.. in proof of person blockchain.
"join group telegram get kicked from admin" - I'm more than sure that you was kicked because you didn't pass bot test.
More than 5K will make running a node unattractive for many.
With current price that is undervalued based on $2M marketcap and 1300 uniqe and equal nodes!
I don't think we will see more than 10-20K nodes, since the return will start to get very low after at 1$ price.
With 1$ DNA price and 10k nodes you will have 150$ monthly for 15 min quiz once per 2 weeks. People work in shoe factory in third world country for 10h daily for less than that.
I would continue to support IDENA even with 5$ per month.
