What do you think? I think I might be close. I'm guessing $10,000 per bitcoin by then.
If the price will be 10k per Bitcoin then you will become a millionaire but the real question is of the price is going to be 10k per Bitcoin. I suggest that you will earn more Bitcoins if you are serious about becoming millionaire. 

If the price of bitcoin rises 40% a year, the price will be 4 times of the present value, or the $2,500. So it is not possible to be a millionaire.

but the question is, if i undervolt my 390s will that impact the hashrate?   Currently I should be able to get roughly 32 MH/s per 390.   If I undevolt , will it still hash at the same rate or will it be less?

Yes, hashrate will be the same. Only problem is if you go too low on the voltage, it will just keep crashing.

Nice.  Thanks.  Is there a detailed guide for undervolting an R9 390 somewhere?  Something that tells me what the best settings are?

You can use the MSI afterburner to undervolt 100mV for both the Core and memory controller.

I use Sapphire Trixx to reduce the core voltage by 200 mV, that will save more energy. But the Core frequency is less than 978 MHz.

The problem with Sapphire Trixx is that it cannot reduce the VDDCI. So I use both afterburner and trixx.

I just watch the Youtube video of Genesis Mining farm.They added a lot of GPU in the past. That could be the reason of the big rise.

If the bitcoin hit the all time high, then the price will be over $1200. That is just three times of present value. So it is possible.

The Claymore new eth miner is about 3-5% faster than the ethminer. Is that also faster than 1.0.6?

Can someone tell me what the -S parameter is used for and also -t 2 option too. Using t-2 works with a number of gpus and some it does not work on. -S I do not know what is for as no documentation I have read so far has this listed.

-S is used for the pools which supports stratum protocol. One of the pool is the ethpool.org. You use -s eu1.ethpool.org:3333

No possible in 2020. Maybe in 2026 you can be a millionaire when the price is over $10,000 each.
6408  Alternate cryptocurrencies / Mining (Altcoins) / Re: Ethereum mining still profitable? on: March 14, 2016, 02:33:10 PM
The Ethereum price has droped from 0.031 to 0.021, that is about 30% drop. Last time, during the correction, the price dropped from 0.017 to 0.008. We may have more to drop.

i doubt it will drop under 0.015, and in any case it is still profitable to mine, around 0.01 or a bit more per card

The price rose to 0.037 or $15 yesterday. It has rise a lot over the last two months. It is the most profitable coin.
6409  Economy / Speculation / Re: 100 bitcoins. Will I be a millionaire by 2020? on: February 27, 2016, 09:55:08 AM
I think the bitcoin price in 2020 will be $5,000 each, so 100 bitcoin is just $500,000, so not a millionaire.

Is it true that gpu with 2gb will be least efficient for mining eth ? What about R9 270x ? How much Mhashes does it produce? Please help me

This is from: https://forum.ethereum.org/discussion/2134/gpu-mining-is-out-come-and-let-us-know-of-your-bench-scores/p10

Is there any parameters for ASUS R9 270x
I have 3 x R9 270x but my average under 30MH/s

Well here's something you can do, assuming they know how to use bitcoins in the first place.

Make paper wallets for each one and give them the decryption password for it. And when you die they can use the bitcoins if they remember the passphrase and they can't take the bitcoins which was meant for the other member as they wouldn't be able to decrypt it.

Print the paper wallets in their name, keep them safe for you wouldn't want them to spend it while you're still alive and when you die they can use it with their passwords.

They may not find the paper wallet when you die. It is better to use a mutisignature system to execute the will.

Give it another few years and your wallet will be linked to your heartbeat. As soon as you cark it your coins will go to predetermined addresses. Job done.

I think it is a good idea if there is no false alarm. If the heart beat sensor malfunctioned, and send the coins too early, you will have nothing left.

What happens if i amass a fortune in bitcoins and i die. Who will guarantee my fortune is divided among those in my Will?

Who would you trust with your private keys?

obviously multisig it. where each inheritor only has 1 key.. that you give them today and the executor of the Will has a key also.
where only at the execution of the will, would all participants collectively combine the keys to send the funds out

what if they lose it, or die also.

Using mutisignature might solve this problem. 5 keys are given to the 5 inheritors, but only 3 keys are need to unlock.

I will bid 0.024. However, it is Christmas time, I am travelling, so there might be delay in paying for the account.

I think the loan of 0.04 is much more than the value of a junior member account. You need a least a high activity full member account as a collateral.

From the 640MB chunk size above, the hash rate changes between 20 to 40 MHz all the time, then it the difference reduces from 20 MH/s to a much lower value. Does it indicate an optimisation opportunity.

Can anybody make the chunk work in the ethminers?

The latest ethminer does not display the hash rate, it makes it difficult to compare the results. I wonder this can be added as well.

Code:
	catch (cl::Error const& err)
{
ETHCL_LOG("Allocating/mapping single buffer failed with: " << err.what() << "(" << err.err() << "). GPU can't allocate the DAG in a single chunk. Bailing.");
return false;
#if 0 // Disabling chunking for release since it seems not to work. Never manages to mine a block. TODO: Fix when time is found.
int errCode = err.err();
if (errCode != CL_INVALID_BUFFER_SIZE || errCode != CL_MEM_OBJECT_ALLOCATION_FAILURE)
ETHCL_LOG("Allocating/mapping single buffer failed with: " << err.what() << "(" << errCode << ")");
cl_ulong result;
// if we fail midway on the try above make sure we start clean
m_dagChunks.clear();
device.getInfo(CL_DEVICE_MAX_MEM_ALLOC_SIZE, &result);
ETHCL_LOG(
"Failed to allocate 1 big chunk. Max allocateable memory is "
<< result << ". Trying to allocate 4 chunks."
);
// The OpenCL kernel has a hard coded number of 4 chunks at the moment
m_dagChunksCount = 4;
for (unsigned i = 0; i < m_dagChunksCount; i++)
{
// TODO Note: If we ever change to _dagChunksNum other than 4, then the size would need recalculation
ETHCL_LOG("Creating buffer for chunk " << i);
m_dagChunks.push_back(cl::Buffer(
m_context,
CL_MEM_READ_ONLY,
(i == 3) ? (_dagSize - 3 * ((_dagSize >> 9) << 7)) : (_dagSize >> 9) << 7
));
}
ETHCL_LOG("Loading chunk kernels");
m_hashKernel = cl::Kernel(program, "ethash_hash_chunks");
m_searchKernel = cl::Kernel(program, "ethash_search_chunks");
// TODO Note: If we ever change to _dagChunksNum other than 4, then the size would need recalculation
void* dag_ptr[4];
for (unsigned i = 0; i < m_dagChunksCount; i++)
{
ETHCL_LOG("Mapping chunk " << i);
dag_ptr[i] = m_queue.enqueueMapBuffer(m_dagChunks[i], true, m_openclOnePointOne ? CL_MAP_WRITE : CL_MAP_WRITE_INVALIDATE_REGION, 0, (i == 3) ? (_dagSize - 3 * ((_dagSize >> 9) << 7)) : (_dagSize >> 9) << 7);
}
for (unsigned i = 0; i < m_dagChunksCount; i++)
{
memcpy(dag_ptr[i], (char *)_dag + i*((_dagSize >> 9) << 7), (i == 3) ? (_dagSize - 3 * ((_dagSize >> 9) << 7)) : (_dagSize >> 9) << 7);
m_queue.enqueueUnmapMemObject(m_dagChunks[i], dag_ptr[i]);
}
#endif
}

Anybody can use bitcoin for good or bad causes. If we use it properly and widely, it means most use of the bitcoin is by good people.
