All i do is calibrate mining units..gather my ores of my 7 Alioth tiles..make elements to sell..but the prices are to low..market prices to sell my products are to low to pay of my tile costs and schematic costs...we need bots back for t1 ores..now with my main and alts...all i do i just pay of my grid costs..and thats not why i pay montly subscriptions for my alts..game is no fun for me this way..I agree with Nick__1

What someone else said, you shouldn't, unless you want to.
 
I've been struggling with that myself. I have four accounts, my main's subscription is lapsing on Monday and I'm considering not extending. The other three have longer (already paid for) subscriptions due to beta subscription issues on my main...
 
The last couple of weeks, constructing more stuff I just wasn't motivated for it. I was trying to keep my ~40 mining tiles up and running and have let that slip the last couple of weeks as well a few times... DU is a grindy time pit, that I'm redoing the same thing I already did the last couple of years in beta (a few times), rebuilding industry and infrastructure. It is boring and quickly losses my interest. And EVE Online (and other projects) have been gaining my interest...
 
What I've considered the last few weeks:
- Giving up completely on DU, it's a timesink that's not very fun a lot of the time and not very fulfilling. It's uncertain future also does not help.
- Just not extending my characters after the current subscription expires and just dip in once in a while when I feel the 'itch'. But that isn't a good idea because my unsubscriped characters will eventually go POOF(tm) and I would have to start from scratch again...
- Extend the subscription for a month and see if we have a good Blackfriday/Cybermonday/Holiday sale in the meantime. Where extending the accounts doesn't feel like throwing a lot of money in a pit, just a little money in a pit...
 
Ingame:
- Deconstruct the 40 mining tiles and put it all in storage.
- But what if they fix the mining pricing just or a few weeks after I put it all in storage?
- Rebuild the factory line again for more efficiency and expand what I build, but it's such a chore...
- Build a couple of ships and do something different in DU
 
Meanwhile it's not as if I have nothing else to do...
- EVE Online seems interesting again...
- I bought a ton of games during the sales that are actual fun to play...
- I have a very fun 3D printer kit (Voron 2.4 350) that takes 30-40 hours to build and would be actually interesting to build vs. redoing the DU factory again...
- Some other fun and interesting tech projects...
 
So yeah, it's actually difficult to let go of DU and in my case that might or might not happen shortly...
 
As for your specific issues:
a.) NEVER run pvp space missions during the weekend! Depending on your timezone, I already stopped running missions Friday afternoon (during beta) as some people pirates in other timezones already started playing. With the current player population, pirate population and only two pvp space planets I'm not even sure how safe pvp space is during the rest of the week, maybe I'll find out...
b.) Currently you can sell your ore at M6 for 13+q/L, all your 450k coal. Also, the weekend might not be the best time to sell as many people want to do the same.
c.) Why are you using 3 accounts to mine just a coal flower? My 4 accounts can optimally (and that might be something different from what you think it is) 'service' 225 auto miners (at max skills), with 3 per tile, that is 75 tiles. Trust me, that's a lot of work!
d.) Always check downtime announcements in the discord if you are doing time sensitive stuff, especially if you're cutting it close. They often do announce late, so you might be buggered either way... 😉
e.) If you're short on cash, do the 180k Alioth mission with you three accounts at the same time (540k per run). You can do that pretty cheaply in an expanded Apex (UEF ship), someone is/was also selling an lvl5 BPC version for it which helps immensely. Add a couple of containers to the hub to get the 30k storage you need for 3 accounts. You can fly the 'cheap' way through atmo, takes about 45 minutes to and from. Or you can do it way faster through low orbit, but that does consume T2 space fuel...
f.) You can mine the 'old' way, but only in asteroids. Might not be your thing, but I wanted to do that eventually as well.

Just because it is an MMO, doesn't mean that everyone should magically HAVE to play with others. 
 
The game was always designed around the fact that a solo or small group will never be able to compete to larger groups or orgs (which is fine). However, in recent times, the facilitation and mechanics revolving around solo play meant that playing this way has become almost impossible to make any headway at all. A solo player should always be able to make progress albeit at a slower pace than larger more organised groups.
 
That is the problem. 
 
It's a personal choice to be a lone wolf even in an MMO game. Forcing the solo lone wolves into game mechanics such as PVP or into large orgs to be swallowed into their machine is a one way ticket to players leaving.

To answer the title of your post... short answer, you shouldn't. We all need to learn how to let things go, this game needs to shut down. It had it's chance, we gave our money, our feedback, our creativity, our effort, most of all thousands of hours of our time. 

I feel people who subscribed for additional years of play time right before launch, when they used fear of missing out tactics before price hike to get us to put money in should be refunded whatever is left, and servers shut down. Anyone who thinks otherwise is in denial of the harsh reality this game will not improve. 

Yeah, I agree. I'm in the same place. Long ago NQ nerfed the ability to mine manually on planet, so the game became pretty boring. You don't really have anything to do while literally WAITING on skills to train other than building valueless little constructs waiting to make enough money to get off-planet to higher tier resources.

Then they nerf calibration exploit so DU is now really just an Idle Clicker.

The ideology behind the economy has driven it into the ground. Base, unrefined resources have more value to sell than high-tier industrial element, and even the base resources are so cheap they are hardly worth idle-mining.

Alioth is a prison with nothing interesting or challenging to do. I'm part of one of the larger orgs and it's still a prison.

I have been a supporter since Kickstarter, but NQ really has done just about everything they can to reduce the value and fun of the game. It seems like such poor decision-making with such great potential. I still have more than a year's worth of DAC just from supporter rewards, and it's not even worth playing for free anymore.

Maybe I'll jump back on in a year or two if it hasn't continued to ride the rocket down into a ghost-town shell of obscurity.

I've played DU for a couple of years now and I'm struggling to find a reason to keep playing. I can't comprehend why NQ is so insistent on forcing PVP: This game doesn't have PVP, and it never has. PVP suggests both players have a chance. If I decide to  fly my hauler through "PVP" space and I get found by a pirate, I am not surviving it. I have absolutely zero chance of getting away. That's not PVP, that's slaughter.

With the market bots being removed from everywhere but Teoma and Jago, the best offer for coal on Market 6 is 10.1 q/L. So, if I want to get anything close to a reasonable price for my ore, I need to risk losing everything by flying through slaughter space.

Industry and ore are the two reasons I'm still playing. Back before NQ decided to nerf mining to death, I was hard core miner. All of these have now been removed to, as far as I can see, create "PVP". The lag is no better, AT ALL, than it was in beta. NQ told us that they were removing mining nodes because, in part, of the lag the mining tunnels caused. Well that obviously wasn't true because nothing has changed.

I contacted support 2.5 weeks ago and have heard nothing in that time. How can support be so much faster and so much better in beta than it is on release?

And don't even get me started on calibrating mining machines. I've had to create two alts and pay for their subscription just to maintain my mining machines. I have a decent coal flower and in a week it mined just under 500kL. Remember when you could mine that in a few hours? Cause I do.

Artificial speed limits when travelling through space and yet another downtime for maintenance in my prime time gaming time made me fail my first ever mission yesterday. I got to 24km away from the drop off point when it failed. Cost me 9 million quanta in quest reward and collateral that I would have used to pay for territories. Now I'm stuck. If I don't spend 8-12 hours at a time logged on, flying through slaughter space, I can't pay for my territories, and if I can't do that then I can't mine and if I can't do that then I have no money. And of I have no money then I can't pay for my territories. Territory tax - what a fantastic idea that was.

I'm seriously struggling to find a reason to keep playing, and at every turn, NQ does it's best to take away everything that attracted me to this game in the first place.
