The idea that, after their evaporation, Planck-mass black holes might tunnel into metastable white holes has recently been intensively studied. Those relics have been considered as a dark matter candidate. We show that the model is severely constrained and underline some possible detection paths. We also investigate, in a more general setting, the way the initial black hole mass spectrum would be distorted by both the bouncing effect and the Hawking evaporation.

    PBH masses near 10^3 kg allow Hawking evaporation to reheat the universe while Planckian remnants comprise all present-day DM without fine-tuning initial abundance, yielding testable GW signals.
