Reading the project, you need fresh people and a lot of money to succeed. Do you have any chances in succeeding or it is a waste of time?
It's not a waste of time. If it is work everything is going to become great! So, I don't understand why you believe so..
POStoken has a big community, DOU could get a big part of that community.
I think it would be a good idea to post an automated google form here on bitcointalk where people can fill in their signed message.
It should be as easy as possible to join and the info should be more widely spread than in a discord.
Dropping to pos holders will create an instant community, and give value to the coin immediately.
The more people join, the bigger the community, the bigger the success.
It is better to to do it personally on discord. As the spam or fake signatures will appear. We have tried for a day with google form and wr had 40-50 fake sign messages in less than 5 hours. On discord we have at the moment 61 confirmed POStoken holders.
