My mining hardware is no longer profitable for most coins. But instead of selling it i would love to hold on to it all and power it up to mine at new coin releases.

Is there a good resource to know when new coins are being released?

Thank you so much for your response. The answer to all those is no. I did update my bitcoin-qt, just to see if it would fix it.

im on windows and trying your suggestion. i downloaded the zip and python and am running the script in elevated cmd and this is what im getting:

"The wallet is encrypted and the passphrase is incorrect"

Should i just give up?

I see a lot of posts about people forgetting their passphrase...but.... for me, i have used it daily for the past year, and it stopped working today! I tried with multiple keyboards, i tried typing it in word and pasting it. NO GO! Here is what happened...

I ghosted(cloned) my hard drive to a new solid state drive. everything is an exact copy, and everything works perfect.....other than my passphrase in my bitcoin-qt wallet doesn't work now. im not stressing out because i have been keeping it cleaned out on a daily basis into my Coinbase account and just using this for mining. I dont have much in it but i would still like some answers. i already formatted and sold my old drive so i cant put it back in for testing. Everything is there, coins, addresses, transaction history, but the passphrase that i have been using every day, and is the same as all my other passphrase's isnt working with my bitcoin wallet.

What would cause this? It is so crazy.
