From the article:
The recent market downturn, however, has left Nvidia with a lot of unexpected extra
stock due to fading interest and market sentiment.
Did they expect the bull run to last forever? The demand for GPUs for
cryptocurrency mining will only surge again if altcoins start to rise again.
GPUs are obviously useless for Bitcoin mining and therefore this whole
plan by Nvidia is heavily dependent on the arrival of another "altcoin
season". If altcoins continue to fade into obscurity, Nvidia (and AMD as well)
will never see a similar interest from cryptocurrency miners again.
It is possible that the altcoin mania at the end of 2017 was a unique phenomenon that will
never happen again.
