As there haven't been anymore complaints, I released the Bitcoin funds on my escrow address to the Crypti team:

This means that phase 4 of my escrow agreement has been completed.

Again, there's still one person remaining who did not claim their Crypti stake. The person holding the private key of address 1N2zCW5wtB3jh8j4jUixMvWGVGi8VQneEb can contact me to receive their XCR.
