How long can the ant miner last
generally, the service life of mining machines is the whole network, and the relationship between computing power growth is the biggest, because the updating speed of mining machines is amazing. If you can't keep up with the cutting edge of the times, it's very difficult to make profits by using the old mining machines. Naturally, this kind of mining machine will be eliminated, short days, long months, but the general mining machines are rarely used for a year
of course, if the quality of the miner is OK, it will be OK to use it for one or two years
if your electricity price is low or free, then your mining machine will have a long service life, because a large amount of mining consumption is electricity
of course, it is only related to the price of currency. If the price of currency is high and profitable, the life of mining machinery will be delayed, and if the price of currency remains low, the mining machinery will be eliminated quickly.

it takes 14 days from egg to small worker ant, through larva and pupa. The egg is white or light yellow, slender, 0.5 mm in size, like a grain of rice. The larvae are milky white, with thin front end and often curved, which is easily mistaken for & quot; Ant eggs;. The pupa is the last instar. The body of the young ants is shortened and does not eat. It is called the prepupa. After the prepupa molts, it is the pupa. The pupae are milky white at the beginning and yellowish brown later. They are often stacked together and mistakenly regarded as & quot; Ant eggs
the life span of ants is relatively long, and the life span of indivial ants is amazing. Some workers can live for 7 days, and the life span of queen ants can be as long as 20 years. But a stray ant can only live a few days. This is e to the clear division of labor within the ant colony and the interdependent group structure. This is the basic factor of its prosperity
Workers can live for weeks to years, while Queens can live for years or even ten years. Ants have a long life span. One nest can grow in one place for one to 10 years. But most of the new queens die
The process of ant reproction is generally divided into three parts: mating, oviposition and nesting. When a nest of ants reaches a certain number, the queen will breed male ants and female ants in advance. When the time is ripe, the female ants will fly out of the nest to mate, establish their own nest, and begin to breed. The offspring will become a new family. Ant is a completely abnormal insect
extended data:
generally, there are queen ants and worker ants of grade 2. At a certain time, unfertilized females and males appear, and some species of worker ants become soldiers. Some species live in the nests of other species, and their larvae are fed by workers of their hosts
the female ant with reproctive capacity, or female ant, is the largest in the colony and has developed reproctive organs. In most species and cases, only the queen is responsible for laying eggs, and in some species, such as the fierce ant, the queen can prey on her own. But the queen can't control the colony
worker ants are wingless and undeveloped females. They are generally the smallest indivials in the population, but the number is the largest. Compound eye is small, monocular is very tiny or none. Jaw, antennae and three pairs of feet are very developed, good at walking. Workers have no reproctive capacity
resources: network ant
therefore, the life span of ants is relatively long, and the life span of indivial ants is amazing. Some workers can live for 7 days, and the life span of queen ants can be as long as 20 years. But a stray ant can only live a few days. This is e to the clear division of labor within the ant colony and the interdependent group structure. This is the basic element of its prosperity
