You can buy a 90 day subscription for $39 and use that miner as they train in space along with your main. OR as you seem to be suggesting, you could stop training your main and train this new miner and not be able to use them and then in 90 days pay $20 to move them to a new account. For the extra $19 ($6 a month) you get to keep training your main AND use the new miner in space.

An even WORSE idea would be to use an open slot on your main account and use three PLEX to train the new miner (and keep your main training) for the three months and then move the new miner to a different account. Total cost that way is $65 ($45 for the three PLEX and $20 to transfer).

Seems to me that for $6 a month for both characters training AND productive in space that is the better option.

Oh, and to your original question, yes, there is many things that makes you more money for your time invested.

But most of these things need huge capital investment ... like T2 invention, capital, super capital production, reaction towers, etc. All of these things are better profit with "less" time investment, but need big money injection.

0.0 mining is the way to go. My miners are 2 months old and i can plex all 5 plus my booster and a hauler in a few days of mining. All 5 of these accounts were plexed from day 1 and have continued to return much more than my investment of a plex per month. 1B ISK a day is a very reasonable goal each play session.
Isboxer is not a requirement as i ran all 7 without it, but it does make assigning drones/locking targets/ etc much easier.
As far as hardware goes, yes if you run more than 8 accounts you will need more than 8 GB of ram. With all 7 at lowest possible settings at 1920x1200 i hit around 90-95% ram usage with 8GB. No problems but it is very close to the threshold.

Don't know how far you've gotten in this plan, but since the ICE is gone for the most part. Multi boxing Mining toons is TOO much work for the profit margin.

It use to be this.

You skill an ICE miner just enough to max mine ICE, then you stop the training on him so you can train another combat toon to sell on the Bazaar. The ICE profits easily paid for the PLEX each month and since it was ICE, you could just check on the progress every once in a while. I would fill up as many as 4 freighters a day... It was a very cool deal, and required so little effort it was almost fun!

then the ICE nerf hit and that is no more.

If you want to make EVE a full time Job, meaning you actually have to be at the computer, ORE will cover that costs of the PLEX, but at a tremendous time cost and frankly will ruin the game for you to be honest.

if your goal is simple to make money, you can start those accounts using the 21 day trial and reward programs (look them up) which in effect will give you about 50 days for free.. That time can get you a head start on skilling COMBAT toons to sell in the Bazaar.

Skilling toons is really fun, just make specialized ones and you'll make a good profit after a 6 month skill time. If you run 10 accounts it will hardly take any time every few days to check on them. If you start accounts in series, older accounts (sold toons) will start paying for a large fleet of Bazaar toons.

IMHO the Bazaar needs better merchandise anyway, as highly skilled GREAT toons are very hard to find.

Have fun and make tons of ISK..

I currently have 8 cooking.

No. You will crash the market. Your profits will decrease over time.

After you have trained them all up for mining, work on getting them trained up to run incursions. It's alot harder to multibox a VG when compared to a mining fleet, but there are a few people that do it, and they rake in about 100mil isk every 4-6 minutes.

Everyone have different goals in the game. Someone wanna be huge manufacturer, someone is ok with his single pilot doing small scale FW PvP or whatever ... sandbox.

Tiberus Mal : As I said, there are tons of things making more profit per hour, but they are "harder". You need to play markets, find products that sell well and have decent profits, manage the jobs etc. but sure, more profit from it.
