What part of the "Dozen 'stable' coin fails in the past years" lesson are you having difficulties with? There can never be a "stable" offer in this space. the stability comes from "free to print money" organisations and the only acceptable such organisations are governments (not ideal, certainly not 100% stable but the only viable one). Everything that still contributes to keep up the speculation hype value of these cryptocurrencies (and a wallet by a wellknown players does contribute to it) is a net negative.
