And dont forget that you can fund only one total newbie. It wont be easy to get that many people.
How many unique users are there now, I would say less than 300.
How do you come up with that number? There are at least 1000 unique veteran accounts in the stakeholder list. In the first 20 pages there are already more than 200 unique veteran accounts already. NEM is also attracting a lot of new members to this broad as well and they start participating in crypto starting here. If you follow the news here, I have been advertising massively in Doge reddit, as well as Reddit front page and there are more than 1000 click-though to NEM front page from Reddit. So 1000 is my guess but probably more unique users than that but you should count it in the registration thread as it is public information.
Now I agree people have 2-3 accounts and possibly more are quite normal. But you should take your time and follow the fundraising rule requirements (mixing the coin properly to avoid taint analysis) and create 10 new accounts/ passwords/ move the money around to see how long and how much does it take. That would be the true costs of people having multiple accounts which is significantly more than having 1 account and 1 stake.
