Thx for quick response. GUIMiner says 536 shares were accepted so I would assume my stats would be visible?

Laptop is not so stressed according to task manager and it's just warm so I probably could optimise it a bit. Anyway, I treat it as a lottery that costs next to nothing so the chance of winning is next to nothing.

I will write my first comment here. I've enjoyed reading this thread including a lot of its history and I've been completly silent but it made me wiser

.

People most often get interested in cryptocurrencies when it gets a loud on this- so typically when the price is crazy pumped up. Some of them might think, why not mine, maybe I'll get lucky. And I can say it makes no sense

.

My thought late autumn 2019 was the same (after reading a lot on forums). I wanted to buy one Antminer S9, with power of 14TH, and I've thought- maybe I'll get lucky. But quick calculation of expected energy bill - 140 EUR (a month) just for mining with probability of hitting a block after 70 years (on average) made me unsure about this Wink

If I have done this, after 1,5y of mining I would end-up with electricity bills of 2500 EUR with no BTC at all. Solo chance says now it would take 207 years on average to hit a block with such hash rate (because difficulty still goes up, more hash power is put into the network). I don't want to imagine what chance I can expect in next year or two.

So I ended up with mining Monero just for fun, and one USB 2pac miner for bitcoin lottery in one PC. After 10 months of mining Monero with hash rate of about 15khash and a little extra Nicehash power (again just for fun Wink

, finally I've hit a block with a luck of about 250% (and that was not a day when I used Nicehash).

So now you can feel what kind of probability we are talking about.

The most known lottery in Poland: you cross 6 out of 49 numbers. 6 are drawn from pool.
The chance for hitting all 6 is 1:13 983 816
You can win 2,5mln EUR

Bitcoin, chance of hitting a block a day with 70 Gigahash (I mine for fun with) is 1:14 993 148
You can win about 180k EUR

Actually buying a lottery ticket every day to win 2,5mln EUR is wiser.

That's just small summary for all newbies thinking of mining with CPU

PS. thank you CK solo pool is here.
At least I could go through this, do some exercises, and read a lot of history to understand what the Bitcoin is really about (now).
