Poland's central bank paid a YouTube star to make a video about a cryptocurrency crash in order to warn about the dangers of investing in digital coins.

The National Bank of Poland (NBP) told CNBC it spent 91,221.99 Polish zloty ($26,764) on Gamellon, a YouTube partner network that has a number of well-known bloggers as part of it, Google, and Facebook's Irish subsidiary.
