What is the speed of Hashcat for cracking wallet.dat using GPU?

[Mem5]

You can rent as much GPUs as you want (Amazon, etc.) if you pay for. Can become expensive.

For example, if a supercomputer could manage 100,000,000,000 hashes per day. Does Hashcat have any limitations?

10 * RTX 2080 Ti => 9,927,360,000 hashes per day => 21993 days => 60 years
100 * RTX 2080 Ti => 99,927,360,000 hashes per day => 2199 days => 6 years
etc.

Roughly, if you want to crack your wallet in 1 year (24/7) you will need 600 * RTX 2080 TI at ~$1200 each (buy), total ~$720'000, which worth ~75,76 BTC.
Your wallet should contain more than 75 btc to be profitable.

edit: obviously I did not add motherboards and power costs etc..
