There are several different types of Bitcoin clients. Header-only clients like MultiBit trust that the majority of mining power is honest for the purposes of enforcing network rules such as the 21 million BTC limit. Full clients do not trust miners in this way.

If you are asking you shouldn't even contemplate...   Wink

With that out of the way I would want a MINUMUM hashrate that would average a block every 4-6 days -- so today around 100 Th/s.  It all really depends on your risk tolerance....

Even with an average of 4-6 days per block it could very easily be 5-6x average for "bad luck rounds".

On average there are 6 blocks per hour
6 * 24 = 144 blocks per day
30 * 144 = 4320 blocks per month

You want 2 so 2/4320 about 0.05% of the network hash rate

Network hash rate is about 66420 TH, so you would need about 66420*2/4320 = 31 TH

But remember that you have to grow your 31 TH at the same rate as the rest of the network in order to maintain your 2 blocks per month.

A side note for this.
With 0.05% of network hashrate, you are expected to get 0.05% blocks, but the probability of getting no blocks in a month is not low. Smiley

You'll need about 20 TH to mine 1 block per month, and about 40 TH to mine 2 blocks per month.

Good luck!  Smiley

I would recommend the two extremes:

Either your hashrate is so small that you won't ever make anything significant and then you may as well be using it like playing the lottery, this is when you're about .00025% of the network hashrate (which is currently about 60PH, so <= 15GH).

or

You can offset the huge variance of luck by mining 5 blocks on average each diff change which means you need to be 5/2016 blocks or .25% of the network (which currently works out to >= 150TH).

Note that the absolute amount of each of these gets proportionately larger with each diff rise.

Depends on which coin you want to mine, if it is Bitcoin, it's is unrealistic no matter how much hashrate you have

There are in fact a few big solo-mining farms already, and they are HUGE. Smiley

BTC-nugget with only 80TH/s and mined 5 blocks in 6 days?  Wow, that's some lucky miner
