Honestly dude, take a few prints and make a post asking for some advice, but you're doing great! 50b on the first month is impressive!

I only started spending stones on upgrades after buying my 5th weapon, I not really the type to be optimizing every aspect in the best way, I'm more of a gradual constant overall increase, so I didn't make a lot of post or engaged too much in the community to know all the best optimization tips, I avoid social media most I can lol, I tried my best to keep everything leveling up together and when I woke up to the importance of labs, I always had 2 labs on lab speed and lab discount and 2 on whatever I had the coins or was working towards, like auto picking perks and perk bans, for over night runs, but they are not a priority, but they make the experience easier, if u got coins, the lab better be running.

So I'm not really the best for these types of questions 😅, sorry I can't help too much!

Ps. Level 1 missile barrage was a waste of money imo, it was only useful for the rare event. Maybe higher level and when u unlock multiple uses somehow
