Working on this to provide wider coverage than specie only. the coverage should be for operational, cyber and crypto-specific risks. Insurers can expand insurance spectrum and keep risk controlled through the capping of each risk.
Currently building a dedicated product, I would be thrilled to talk to you to get «B2B customer need».
I share with you the fact that it should ultimately be a B2C market but very difficult to initiate a project (and get resources) at insurers with a B2C product. The need for insurance of small investors is not obvious since Ledger HSM exists. Still an opportunity for investment funds or some post-ICO projects in the «b2c/selfcustody» market. Otherwise exchanges, custodians seem first targets for insurers willing to jump in.
