So since we are allowed to multi-account I figured I would share the current best way to make N-meseta.
Making multiple accounts to do weeklies. It takes about 15 minutes to do your daily's so you can do those on multiple account. So if you have 2 hours per day to run daily's you can complete weeklies on 8 accounts earning you 4mil a week. if you grab alpha reactors daily you can get an extra 292k a day. for an extra 2,744,000 a week from that for 8 accounts. If you can make more accounts you can earn even more N-Meseta. I think the limit for this would be about 50 accounts. Earning you about 42mil a week.
You can also get the red boxes on each of the accounts and event rewards if you have the time. Also during the event you have to do less daily's to get the weekly's done.
You can get the N-meseta back to your main account by selling N-grinders for weird amounts so you only need prem/shop pass on main and put up like 527 grinders for 489k or something. All you have to do is match up the price and amount. However you lose out tax from this.
All this is exponential if you do this early and buy up AC items to scalp later.
Proof from support you can multi account
