Hi! I really like crypto sessions and I like your idea.
It would be nice to have the kind of a "lock" you proposed. I think especially the Price Lock option seems really cool and could help people from overtrading.
At the moment, when I want to stop myself from reacting to minor changes in price, I put my crypto in one of the many earning pools or stakings available. That way, (especially in Locked staking) I lock the desired amount for a certain period (3 months) and just forget about it. That way, my amount is far from my fast-reacting hand, plus I earn some money. Maybe that can help.
On the other hand, your idea should be smartly developed because what if you lock your crypto in Price lock, and the crypto never reaches the desired price? Also, what would be the advantage of your idea compared to the stakings and earning options?
