Tried to use it with 4400+ SP available. Had something like 9.1 TRC. Tough luck, discounted account was 9.4 TRC. Tried again with 4700+ SP Tough luck, discounted account price had climbed to 10.1 TRC. "The system" doesn't want me inviting people to steem it would seem. So I just delegated my SP to for-profit bid-bots and started focusing on other opportunities.

Because obviously for-profit bid-bots are the Darwinian winners in the steem system. Survival of the fittest. It's obvious for-profit bid-bots are the fittest "organism" in the steem eco-system and no amount of idealism from @pharesim and other well-intentioned people is going to change that. Memento communism - a very humanistic ideology ... until it leads in practice to survival of the fittest: Stalin
