When Celsius issue happened, I saw a video of him:

Peter Schiff Exposed Mashinsky’s Celsius Scam Seven Months Before It Imploded

In it he repeated that bitcoin has no fundamental value, and that it is something of a ponzi scheme, saying that the price at some point in the future will collapse, with the price going to 0.

With those arguments, no matter what happens to his business, I don't think he will ever buy bitcoin.
