1: do NOT loot the bosses until you finish the astral sector, once you have killed the bosses, then loot them, then you can leave, make sure though that before you do a astral sector you are near a item seller.
2: equipment upgrading, use the gold you make from astral, it will cover it easily, runes you just need crystal chips from the participate and win daily feature, you don't need to buy them from crystal exchange until you hit 7s in runes then you will need to, but 7s are enough for now.
3: Find something you don't buy in boutique on Auction House and see if that sells well, it is trial and error, i found something nice i can make a lot on and i could make 200k+ a day if i had better internet.
4: only way to make 60 million in seconds is if someone gave you that amount or if you got supremely lucky, now if you do get a stronbox and you open it, it has a chance to become 10 strongboxes DON'T open them, sell them for 3m the lot, tick, you just made 10x the amount you spent on just 1 box.
5: Take time, always let whoever is stronger get the mercs as it is all about stats/gear in them sectors, avoid aoe attacks, but overall be patient with it, all of them are easy to do.
6: Then make some, join a guild, get a group of new people and start working together, that one only you can figure out.
7: Mysterious sectors is what you used for leveling up and for reincs, it is kind of simple compared to normal astral, Anomalous sectors you need a group, otherwise it will be hard and you need to level your ship up to the best stuff that you can get.
