That's right, my friend! As the bit size increases, it gets more difficult. Algorithms like BSGS and Kangaroo easily crack small bits, but they need the public key! That's why it's important to use Marapool for secret transactions to prevent bots from stealing your funds. If I'm not mistaken, whoever found bit 68 was robbed.
The last puzzle was solved in April of this year: https://btcpuzzle.info/puzzle/69
That's right! Puzzles 69, 70, 71 onwards remain unsolved.
No it looks like 69 is solved as is puzzle 70 which was found in 2019 before the site made snapshots by the looks of it. 71 is still fair game.
