I'm not sure if either is appropriate. Bitconnect is worth nothing, so no matter how many bitconnect coins were lost, they would be worth $0 not $3B.

The title seems almost unrelated to the article. The title refers to money lost in the bitconnect ponzi scheme, but the article is mostly about kidnapping schemes worth much less money, and that demanded payment in bitcoins.

Bloomberg is biased against cryptocurrency. As everyone knows Bitconnect was Ponzy scheme it would not have made sense.
