1 The speculators are the natural floatation force to sell at a high price, hence helping the buy side to get higher. They usually have bots 7/24. As long as there is chance to see <1% spread, there is business. So our job is keep giving the chance.
2 When BTc starts to fall or just stops having its upward momentum, people start to think of buying nubits or postponing selling if they know there exists chance to sell at $1 later. There will be increased chance (“a greater percentage of the time”) the peg is maintained.
3 Once the percentage is 100% or can be offsetted by park rate reliablly, T5 kicks in.
