40 Riverside Drive

This 10,720-square-foot, 32-foot-wide mansion with Riverside Park as a backyard and river views was built in 1879 as part of the Upper West Side's "gold coast." When hedge fund manager Roy Niederhoffer purchased the home for $12.9 million in 2013, it had been split up into multiple units. Niederhoffer restored the six-story home to its original mansion-style glory and is now selling the home for just under $16 million. The grand home at 40 Riverside Drive is possessed of the city's third largest ballroom in a private house, and as Bloomberg reports, the seller is accepting bitcoin, as he's a fan of the cryptocurrency.
