To conclude, we expect the GW events due to compact binary coalescences to be registered already by the initial laser GW-interferometers of LIGO/VIRGO type at a rate substantially higher than has previously been thought. We also think that BH will thus be detected simultaneously with GW. Otherwise, we will have very stringent constraints on BH formation parameters, which is, of course, much less interesting.
