SO I may have gotten lucky and found an old screenshot of wallet that contains a Hash160 address. That is the public key right? Please tell me I just got lucky and can use the kangaroo stuff above?
No, with that Hash160 address, you calculate your Bitcoin address.
For example : 1B2Q8vPm5E5b8yxaNWUW5ZfdCR5Zu1KMJn - is the public address
