You invested 6k STEEM into a structure that from day 1 said it would only pay out 80% of it's income.
Break-even for the few top "investors" was completely impossible to begin with... unless even bigger whales started spending later on.
This was clear from the get-go due to the progressive upgrade costs and the payout structure and it has hardly changed at all with the progressive rule updates.
If you got into this to make an ROI... then you made your mistakes two weeks ago and these combat rules changing has very little to do with it!
