I'm not sure how they calculate and categorize how much power consume to mining in a country, even in China where the biggest mining farm located can't compare to the whole country's power consumption but it's clearly different if we compare to Africa, pretty sad as mining uses more energy than Ecuador (https://www.newscientist.com/article/2151823-bitcoin-mining-uses-more-energy-than-ecuador-but-theres-a-fix/)
Blockchain implemented proof of work which cause a lot of energy used everyday, it's make sure bitcoin is something that really worth.

Customers wouldn't be happy about BitMex decision.
If BitMex could managed sold bch at the peak, maybe their customers won't complain.
Seems they do not like hard fork at all, don't want to credit their customers either with bch or b2x.
And have tried to dumped bch after it pumped significantly over $1900 few days ago.

Bitcoin will reach $8000 across global exchanges soon, and some exchange such as OKCoin and BitHumb may reach new ATH faster than others as traders and investors in Asia seems daring to take risks. People always speculate bitcoin be able to reach certain price in this year, honestly; bitcoin reach $8000 in this month is beyond my estimation, but we can't be sure about its price as huge influx of money have been invested in this market and investors don't want to miss this opportunity, although they just see it as an speculative object to gain profits. So, bitcoin may reach $10,000 by the end of this year.

Well, I can't calculate your ROI correctly because you did not mention how much you spent to build your mining rigs.
If just calculate L3+ and PSU it will be = $33,535
Based on nicehash calculator, 1 antminer L3+ could produce $650/month. As you have 19 L3+ = $12,350/months
You may achieve ROI within 3 months, am I wrong?

One last question; where do you live? as you may hosting for a couple machines, maybe some people who stay in the same city probably want to contact you. Thanks.

All of those ASICs are L3 machines?
People tend to calculate profits based on bitcoin or litecoin prices.
And I have heard some miners talked the same thing which L3 is more profitable than S9.
But, Antminer L3+ more expensive, like $2250 for each. Which mean, it takes a longer time to achieve ROI instead of buy some Antminer S9 that cost around $1250. I realize ASICs price from bitmain always change in every batch, for next batch will be; $1415 for S9 and $1586 for L3+
How much it cost for 1 Antminer L3 when you bought it?
How long it takes to achieve ROI for your investment?

Actually it make sense to generate profits by investing on cloud mining.
Mining will be profitable if bitcoin price increase over time, as the difficulty increase as well due to more and more mining hardware get into business.
But, consider the risk; you can't control the profits as "cloud mining owners" will decide how much you get, based on their income every hour or every day. Look at genesis mining; many people claim it's not profitable anymore due to some reasons and hashflare seems turn into "shady" business recently.
So, if you want to mining, just buy ASICs hardware and do the real mining in your place instead of buying unknown hash rate from cloud mining which you don't know whether you get fair payment or not.

It's 20% loss which calculated from all time high.
How to calculate:

To calculate percentage decrease:

First: work out the difference (decrease) between the two numbers you are comparing.

Decrease = Original Number - New Number

Then: divide the decrease by the original number and multiply the answer by 100.

% Decrease = Decrease ÷ Original Number × 100

Let's say bitcoin ATH is $7800 and it plunged to a low of $5507 which mean:

$7800-$5507 = $2293 (decrease)

% decrease = $2293 ÷ $7800 × 100
% decrease = 29.39
decrease = 29.39%

It's happens like few times, bitcoin price drop back and altcoins rises, but in the end bitcoin always recover and reach new ATH.
None of those altcoins could replace bitcoin as the first and the king of cryptocurrency.
Bitcoin price declined significantly, mostly because blockchain network get flooded with hundreds of thousands of unconfirmed transactions and bitcoin hashrate have switched to mining bch as it's more profitable right now. But, after difficulty adjustment done, most hashrate will return to mine bitcoin and bch will fall again.

I would like to participate,

Obviously, a country which has regulations regarding bitcoin and tax it as capital gains, such as in US. https://www.investopedia.com/university/definitive-bitcoin-tax-guide-dont-let-irs-snow-you/
On the other hand, in a country where people could easily use bitcoin in daily transactions in Japan, there is no tax for trading bitcoin. https://cointelegraph.com/news/its-official-japan-has-eliminated-tax-on-bitcoin-rise-in-trading-expected
But in most countries that don't have any fixed regulations, you are free to trade bitcoin and don't have to pay tax, but only fees to exchanges.

Best way to invest; by learning about bitcoin as a digital currency, it meant to be an alternative currency, or become major currency in the future.
Or else, if you have a business which offers product or service; you can accept bitcoin payment (one of the best way to earn bitcoin)
If you want to invest; just buy bitcoin in an exchange, local exchanges in your country maybe the most convenient as you can deposit through bank account, and vice versa.

Yes, it's monero, altcoin mining. But the risk to break your phone due to over heat and push the cpu, it's not worth.
People can't mine bitcoin easily through CPU, GPU, browser phone or tablet as it's not profitable and not worth at all compare to the risk, you need real hardware such as antminer s9 to mining bitcoin. Just simply like that.

We have been waiting since October 25, then November 1st, and finally November 12th, free air drop seems like free money in most case as people tend to sell it after get listed on exchanges. But, some questions remaining: which wallet developers, exchanges and pools that support bitcoin gold?
I know waves wallet is the first one which declared support btg, but is there any other? How to synchronize my btc wallet and waves in order to get btg? using private keys? is it safe?

I'm impressed, your site is very informative. Seems I can find anything > useful information relate to cryptocurrency.
I've seen lots of crypto-sites but you have the best site which provides the most complete directory.
Well, it's easier for newbies to learn about cryptocurrency, wallet, exchanges, even find a job through cryptojobs by searching in this site. Well done.

Bitcoin must crash? Seems very imposing.
I don't think $7500 is the peak, bitcoin even reach $7800 yesterday, don't you know that?

And then 2x hard fork suspended in order to keep community together, but people's speculation divide into two groups; bitcoin will rise or bitcoin will fall. Consider current price, bitcoin seems losing its value after reach the peak, but I don't think 2x cancelation will affect its price significantly. I guess bitcoin will stand over $7000 as the new bottom line.

Probably not, 99%.
Bitcoin price will increase towards $7500 again and reach $8000.
If bitcoin price drop back, it won't fall further than $5500.
There is no reason for bitcoin price decline at this point, 2x suspending is not a big deal as segwit could afford current transactions.

LoL, your friend is a right brain user , he's right about bitcoin isn't anonymous, as it's pseudonymous. Fiat currency is the most anonymous as long as it doesn't going through banks system.
Most people (99%) still using fiat currency, only few place where we can spend bitcoin directly to the market.
and bitcoin just 9 years old. Give it another 10 years and we will see what happen in monetary system.

Only works if clients are bitcoin user as well. There are a lot of people here offers product or services which accept bitcoin as payment method.
For people who lives in a country or city where bitcoin has been known for years, such as in Japan or Arnhem city in Netherlands, you can find lots of merchants or freelancer that accept bitcoin payment. But, in most countries especially in third world country, bitcoin is still not well known and maybe there is no any merchants accept bitcoin.

Genesis mining will offer new contract soon, but I don't think it's fair for new investors, as many people claim didn't receive full payment which always decrease over time and sometimes you have to wait for a long time to get payment. You may consider this risk.
Buy and holding bitcoin seems more profitable for me, as bitcoin price may increase over 100% in a year,on the other hand, it takes 6 months to achieve ROI from genesis mining.
