You've got a NY Central park facing apartment. When you are going to sell...the likely answer is never..lob it to your descendants.

In fact that’s one valid option!!!
Btw how much is NY Central park facing apartment? Never thought about it.... 2 beds at least? Just to estimate Bitcoin price

typically, low to mid 8 figures.
