like that.. if you run now your hashpower (example a RTX3080-3090) to mine coins...
lets say, the wallet needs >10 Years to Crack... (then Lucky you)
But you better use your Hashpower to generate Coins for the next ~5 Years.
5Years = ~ 50.000 € and after another 5 Years (then the coins are getting more and more Value) you have roundabout 1 Million €
Time is on your side

Funfact... some Ppl don't get MD5 hashes cracked from hashes.com with over 10GH/s but think to break Wallets with 15kh/s

1 kH/s is 1,000 hashes per second (sometimes mistakenly written KH/s).
1 MH/s is 1,000,000 hashes per second.
1 GH/s is 1,000,000,000 hashes per second.
