Cryptocurrency is already under the scanner of government agencies. They have associated it with everything which is illegal.
After reading the story of this couple I am in the conclusion that they are wrong on their part. I have no doubt about it. They should immediately do something to repay their tax.
If they need to sell their crypto assets then they should otherwise, the tax agency would suggest the government that cryptocurrency is a new illegal way for them to abet tax.
It does sound silly but, it will happen for sure.
They should do that and they should've done that in the first place because if I'm not mistaken, authorities know that they have a huge cryptocurrency asset which got revealed when it got reviewed again.
They are probably waiting for the price to pump but they probably predicted it incorrectly to the point that the due date to pay their liability came. I don't know how big this would get but it's still trouble for them.
