I think it would be a shame if SoundCloud disappeared considering how many of my music discoveries come from there. If it wasn't for SoundCloud I wouldn't have known Pilotpriest, Dance with the dead, Droid Bishop, and other synthwave artists even existed. Bandcamp is okay but I find it hard to find new synthwave and related genre artists on their search. If SoundCloud dies someone over at Bandcamp needs to beef up the search and tagging system over there (I buy much of my music now through BandCamp).
