Does anyone have the public key of 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN puzzle #64 or is there a way to figure out the public key of a public address?? I'm so confused I've been running cuBitCrack on tesla v100 for almost a day and I figured that Pollard's kangaroo for SECPK1 would work a lot better than cuBitCrack please help

Try Bitcrack2 it has a great random stride from 1 to 32, uses public address not key. With a fast gpu like yours it may do the trick. I ran 4 gtx 970's for 4 months non stop and only got a large electric bill on 64. Looking at the previous keys found my bet is on d, e or f and probably uncompressed since the keyspace is not that big and no one has found it in a few years and most try compressed. Good luck

You can't use a program that uses public key for 64. All we have is the public address for 64.

It will be a compressed key, as all are. No one has found it because only around 13% of total keyspace has been searched. Maybe add 1 or 2% to that for a total of 15%, but that is probably all that has been searched.
