Mining on foot
bitcoin is a kind of network virtual currency. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

Sports earning is deceptive. Taking Changsha as an example, it was investigated by the instrial and commercial department for its illegal activities such as pyramid selling, illegal fund-raising and financial fraud "you can make money on foot" has attracted many users. As of September 2019, the number of registered users of "qubu" app launched in 2018 has reached 73 million. However, recently, he was suspected of pyramid selling, illegal fund-raising, financial fraud and other illegal activities by Changsha instry and Commerce Department for investigation extended materials: low registration threshold, convenient participation, and promise huge returns are the key to the successful weaving of "fun step myth". To a certain extent, it really hit the "careful thinking" in many people's minds that "you can make money even if you lie down". When the traditional mode of MLM cools down, we need to be vigilant that the MLM pattern itself is also evolving however, the "fun step" app is full of chaos, but there are many users, which indicates that the public is not aware of the new pyramid schemes and scams. Although "qubu" has been investigated, there are still apps that "watch news to make money" and "swipe short videos to make money" users should be alert to some so-called "making money" apps. It seems that there is no profit, but in fact there may be a huge consumption trap. For example, the platform may use users' video brushing time to play some false advertisements, or set up various "obstacles" in points exchange and cash withdrawal source of reference materials: People's website - walking to make money "dream" is shattered, and "interesting step" scam is finally exposed 
In addition, when software is applied, users need to provide ID number, bank account, WeChat account and Alipay payment by 1 yuan for registration. Through this link, the platform obtains a large number of users' personal information and location information, which may be leaked to a third party for profit

mining output formula:
the total development of sports currency is 1.2 billion, Annual output halved
A = total reward / day (1643835 coins in the first year)
b = average user's completion (5000 steps to reach the standard)
C = average user's hardware computing power (1% of the total output)
d = average user's output / day
e = average user's hardware computing power (99% of the total output)
F = average user's completion rate And
G = personal completion rate of the first generation of coin sport Bracelet users (10% in 2000 steps)
H = output of the first generation of coin sport Bracelet users / day
daily output of ordinary users:
d = a × c ÷ B
daily output of coin sport generation Bracelet users:
H = a × e ÷ f × g
Just got the potatoes in the barrel, now you can bake them directly
What if there are no potatoes (or potatoes will be scarce in the future)? We can try fishing
put it on the fire
Introction to food types
fish, beet, potato, coconut, shark meat
food may not be eaten only after it is cooked, but it can also be eaten when it is raw

hold down the left mouse button to store the force and cast the rod. The length of the rod depends on the time of storing the force, but... There is no difference between throwing far and throwing near. You can catch fish at the same time
when the fishing line sinks slowly, the fish is hooked. At this time, press the left mouse button to finish
get delicious fish
put it on the fire

Survival of rafts water resources acquisition and drinking methods, come and have a look
the acquisition method is shown in the figure:
when the water is cooked, press the e key to obtain drinking water
after getting drinking water, press the left mouse button to drink
the empty cup can still be used after drinking. Continue to repeat the action just now to get more water
drinking water is not the only way to get thirsty. You can also eat food to get both satiety and a little thirsty (coconut can get more thirsty)
