Washed-up rapper making FUD on BTC.
He was previously into it, even releasing a track called Bitcoin. I think his change of heart reflects the general sentiment of the market. If you're still hodling, are you smart with strong hands, or simply deluded?
Everyone loves it when they think it's going to the moon. Not so much during the hangover period.

He probably wrote that track during the 2017 bubble -- it got released on a 2018 album. Now that Bitcoin is in the dumps, he's giving it the cold shoulder and calling it dead like most of the mainstream. Like you said, it's just a reflection of the general sentiment right now.
