900x RTX4090 if you had honest access to that:
I could provide this data it would take 32hours to search each iteration using 900 x RTX4090 at 4billion keys per second each

#66 has 68 iterations would of been a 2176 hours without pubkey for all but it would of been found after 544 hours
#67 has 60 iterations 1920 hours
#68 has 62 iterations 1984 hours
#69 has 73 iterations 2336 hours
so Im saying max 6240 hours or 260 days to find #67 ,#68 and #69 if I had 900x RTX4090s

#70:349B84B6431A6C4EF1  has 98 iterations 3136 hours without pubkey but it would of been found at 2048hours

Currently it would take me 2970days just to search 1 iteration so 900x RTX4090 is insane amount
