Hello all, I been a long time reader here but have only recently signed up.
I started mining bitcoin in 2015. I saved up and brought 2x second hand s3 antminers and a 1x s1 antminer, I was really interested in the blockchain tech and had to have a piece of the pie.
I mined just over 4btc which had been sitting in my blockchain.info wallet. One day I couldn't access my email due to wrong password, I finally got access back into my email and noticed a few emails had been deleted as well as the one which contained my wallet details, lucky I had a .txt backup. Urgently I log into my wallet and found I had been a robbed, all my btc was gone. My heart sunk, I feel so bummed all that work and money for nothing.
My advice is
Dont keep you wallet details in your email or online at all.
If you have bitcoin dont tell anyone
Use an offline or physical wallet
Dont make the same mistake as me
It's hard to swallow this because BTC is pretty expensive now, 2 BTC can even buy cars and real states this days, by the way this must be a lesson for all of us. TBH I don't really trust online back ups because I always felt unsecure not because some else's know my password and email (not because of that), but because I think something higher are controlling all of the information in the surface web, remember what Snowden have leaked?
Write it down on paper bro and keep it on your own secret vault in your own room. And yes listen to their advice, hardware wallets are always the safest (and keep your wallet in a safe place). You're a miner and I know you know a lot of stuffs (hardware and software but never ever forget that even if you are busy working always safety your treasure first.
You're just going to cause a heartache to yourself when you lost what you are working so hard.
