What excavators are used for mining? They are cost-effective
computing power is the ability of a machine to perform operations, that is, how many hash operations can this machine perform per second. At present, the computing power of the mainstream bitcoin miner is 14T, that is, hash collisions of the 13th power of 14 times 10 per second
power consumption is an indicator of the power consumption of the miner ring operation. Electricity consumption will have a huge relationship with mining costs. Generally, a miner will operate 24 hours a day to excavate, so the power consumption sometimes seems to have a small difference, but in fact, the cost gap is relatively large
here is another little knowledge, that is, digital assets of the same algorithm can be mined by the same miner. For example, bitcoin miner can also dig bitcash, Ethereum miner can also dig Ethereum classic
for more professional knowledge, it is recommended to consult the honeycomb miner. There are professionals to help you select and answer for you. The boss comes from the fire coin, and I feel reliable after personal experience.

How to kill the stone giant in ark survival and evolution? Many novice players don't know how to kill him. Here's how to play the stone giant. Let's have a look
stone giant's fighting method
if you kill, just shoot with an arrow, card type. Be careful that it will throw stones. If you train, use a gun or RPG
the above is the playing method of stone giant. I hope it will be helpful to all players
1. Stone man is very good at training, just take RPG directly. You can try to use a circle around the giant beast gate to lead the stone man in and trap him, and then hit him in the head with RPG. The stone man will feel his head, and it is said that he will feed the stone or sulfur stone after fainting. You said you were going to use an anesthetic arrow? Nono, anesthesia immunity. You said you were going to stun with a stick? You can have a try
Of course, stone people like to eat Mantis eggs most. what? You said you couldn't catch the mantis? Well, I think it's better to just grab the Stoneman. After training, you can collect stones, attack with the left key, throw stones with the right key, turn C once, and then swing a circle. You can make stones out of everything. The building owner thinks that DLC is the strongest creature, immune to magic damage. All dragons are immune to right key and physical damage by 90%. If you catch more housekeeping artifact, you can also turn into stones. After killing, you can dig out five kinds of materials. You can kill one of themDevelopment:
1. The independent studio of "Ark: survival and evolution" released their new work "Ark: survival and evolution", which is a new open world multi person survival game with dinosaur theme. This game is expected to be launched on PS4, Xbox one and PC platforms in early 2016, but before that, the game will be launched on June 2, 2015 through early access plan of steam platform
2. "Ark: survival evolution" will be created by fantasy engine 4. This game will focus on survival elements and mix unique elements of multi person cooperation and competition. At the beginning of the game, players will wake up in a mysterious island, and there are a group of people who are also in chaos. In the game, we need to survive through hunting, crafts, research technology and other ways. In addition, players need to establish shelters to protect themselves from bad weather, dangerous wild animals or potential enemies
Ark: survival evolution ol taming rock giant strategy, for this game, many small partners may not know Ark: survival evolution ol taming rock giant strategy, the following small bone to bring you Ark: survival evolution ol taming rock giant strategy related information, the players who are not clear come and watch with strong ~
together Rock giant It can live in peace with most of the burnt earth creatures, but it has a strong hostility to human beings. In addition, the setting of this fantasy creature is all that a rock should have:
You can't swim and sink when you enter the water. You can only walk slowly on the bottom of the sea. If the tame stone man is accidentally dropped into the sea, without Canglong, we can only build a gentle slope to let it walk up slowly
Fortunately, it abides by the principle of being a stone and can stay at the bottom of the sea quietly waiting for rescue without breathing. In actual combat, there are also tactics to sink the stone giant into the water
It is an excellent MT: it completely ignores the breath of elemental dragon, can be immune to most abnormal states, and has considerable resistance to most attacks, but explosion and armor piercing attacks can pose a greater threat to it
Skills
1 First look at the picture and experience the spirit < img src="">
Of course, it doesn't need such rigorous construction method to block this slow-moving, bulky guy. Six to eight metal pillars are enough. Some old drivers are skilled enough to carry a gun on giant rhinoceros and Fengshen. They can successfully stun the moving rock giant, but Xiaobian doesn't recommend novices to do so here
Artillery is a weapon that can cause great damage to the rock giant. It can't cause vertigo when it hits the body, but cause a lot of damage. It's not easy for the artillery to aim, and it may kill the rock giant if it misses a few times
Rocket propelled grenades can also stun rock giants and save resources more than artillery. But its efficiency is very low, taming a stone man may need to carry several RPG bobbins. And if RPG Gunners want to avoid the rock giant's throwing attack, the probability of error is high, and the artillery ignores the throwing attack. The process of operation is the same. Different people have different opinions on which weapon to use
Feed
1 Mantis egg feed, sulfur, clay and stone can be used to tame rock giant. Taking the 150 rock giant as an example, 35 parts of Mantis egg feed can be tamed in 25 minutes, and 553 parts of sulfur will be used instead, consuming 8 hours and 23 minutes. As for clay and stone, I don't think you're interested in listening any more. Sulfur is not rare in scorched earth
Mantis egg feed is not easy to come by, and taming Mantis must be & lt; The horn of the dead worm & quot; As feed, death worms are not easy to find, let alone challenge. At the same time, the conditions for Mantis to lay eggs are troublesome. It doesn't accept the bonus of egg stealing dragon. It has a slightly higher probability of laying eggs in unknown areas (such as Jiaotu desert, central island Eagle Island) and when the wind is small. Secondly, it doesn't lay eggs when there are people around. It can only get stuck in the time when the eggs are refreshed. If you go to see and pick them up every 20 minutes, you will get nothing if you stay there for a long time
Because of the rare Mantis eggs, sulfur is widely used to tame rock giants, although it takes a long time to tame
Location
1 Rock giants are very common creatures in scorched earth, but Xiaobian would like to share the map with you Even if you don't grab it, it can be used to hide
Probability of occurrence Green & gt; Yellow & gt; Orange & gt; Red
Red There's a whole map. I'll ask you if you're afraid
