Hi guys I’m new,not to computers but here,I have old Bitcoin wallets I need to run though a program to see if I can recover my passphrase for,I think a 2 core RTX 4090 computer running for a year should do the trick but wanted to talk to you about Lambda,would you recommend there products do do this and if yes which one should I purchase,all I need the computer for is this 1 purpose,I will load the wallet into the program,let it run and walk away,it’s a expensive item which I have no problem paying for as the bitcoin I have is worth it but don’t want to spend the money and then get it here and it’s not right for the job,please advise me thanks.
