This Daily Mail piece (I know, DM), connects many, many Russian/Trump dots.
No excerpt could do it justice, but here's a bit.

There are a lot of suggestions that Rybolovlev drastically overpaid for this property, said lawyer David Newman, partner in Sills, Cummis & Gross of New York, who represented Rybolovlevs wife Elena in her divorce from the Russian oligarch. If you look at the four years between Trumps purchase and his sale to Rybolovlev, there were very few things that increased that much in value.

It is notoriously difficult for Russians with that scale of wealth to continue to prosper without the approval of the political establishment and that usually means the new tsar himself. Oligarchs such as Mikhail Khodorkovsky who have rebelled against Putin have been imprisoned. Others, such as Boris Berezovsky, have met unexplained deaths.
Rybolovlev had risen quickly in the violent wild west world of post-Soviet Russia. In 1995, at the age of 29, he became chairman of the giant Uralkali empire.
But Rybo wanted to move as much money as possible out of Russia, where both health and wealth can depend on remaining on good terms with the Kremlin.
This explains his interest in buying assets in America. But the value of Trumps Florida property dropped precipitously after Rybolovlev bought it.
