The Nimiq Team should consider to allocate resources for a Ledger Live integration, which would enable staking for a very wide audience, and also decentralize the Nimiq staking gateway itself.
Ledger is a massive and established brand (152k members on Reddit, etc).
Cost estimation ?
The Kaspa community collected about $30k to get it done by an indipendent developer of their community, and the process is about to be completed after 7 months. I think that with a more streamlined process this amount could be reduced significantly.
