Hello guys!

I just found on eBay some Bitcoin miners for beginners :)
I saw someone here have something similar, so I would like to ask if it is worth buying one?
How much Bitcoin (satoshis of course) can be mined with these daily?

Sellers say in description, that is easy to install and use, just need to connect with phone / PC, set up the WiFi connection, and introduce the Btc address. It would be that simple?
Please, if anyone has experience, share it with me...because if it is worth it, this is what I'm asking my wife for my upcoming birthday ;)

Thank you!

99.9999999999% chance that you buy the thing and pay about $1-2/mo in electricity to keep it running for the rest of your life and get zero reward.

0.0000000000005% chance that you solo mine a block and get generational wealth

0.0000000000005% chance that you solo mine a block but didn't setup your address correctly and effectively burn generational wealth.

At least with a real ASIC machine, you can get a steady sats flow and can use the heat for other things.

If you are getting these to mine BTC, you might as well try running BTC collisions. It's like playing the lottery every 10 minutes.

If you are getting these for fun, and to learn more about BTC mining, definitely worth it.

I wouldn't even call that gamble

Bitaxe is a nice alternative with higher hashrate, and an s9 is 150$ and can be plugged into a normal 120v wall socket.

I have an old laptop sitting here, I was wondering if it would be worth running as a miner and joining a pool. Really don't know what goes into it.
