Sweating is about connecting the beginner entropians with the experienced entropians. A sort of one feeds the other and everybody's happy in the end. A mutual agreement to produce and buy/sell from each other.
As sweaters collect their sweat and turn it into welding wire or mind essence, the free-to-players produce something for the space and vehicle owners/operators. Still low-cost for either. The difference is measured in $100's of dollars, sometimes $1000's but really the amounts connecting are low.
A low-end stock for comparison might sell $100,000 in a day in a few seconds, no problem. In entropia moving that amount would have a huge effect on whichever market it was in. In stocks, a 5-10% blip of $1,000,000 or more is in a typical day (minute) and does not have much effect. (need a chart and trade records to show this, an IBM ticker symbol on a finance site and some sample trades)
Sweaters collectively, however, can approach I would guess $200-$500 a day (24 hours). That's the pool of demand available. It varies but generally within $100 up or down in market volume. Split that by who knows how many sweaters to arrive at a typical sweaters' experience. I would guess some 200 sweaters in a day. Large enough however to fuel a lot of play.
Keeping in mind the $1 per hour cut, sweating can still be profitable as outlined in an earlier post.
As the spaceship owner/operators need welding wire the sweaters will be there to provide it even at breakeven or a loss as 'it's just a game', 'sweating is free', and 'sweating builds skills'. The three reasons most cited, particularly skills, give the new player an opportunity to connect with the spaceship owner/operators who are buying and selling goods between planets. Also to mainly build their own avatar's skills. The sweat sold contributes to keeping the spaceship people with operating spaceships.
Sweaters are connected to the in-game economy in important and satisfying ways as other professions are connected to sweaters in satisfying and important ways. Join the sweaters. Join entropia universe.
sidenote: annualizing the average sweat demand over a year is $127,750 of sweating per year. and by 200 sweaters about $1-$2.50 per sweater per day.
