Investment in 120 cloud computing power: 3% in the whole year

1. Of course, I'm investing in ancouli now, and the amount of income is OK, mainly because my friends are here, and the guarantee money will be returned on time

2. This is the simplest digital currency investment at present. Just pay for the platform. Maya cloud computing has its own mines and mining machines. The management team is responsible for the operation and maintenance of professional mining machines and mines. The consumer of cloud computing, that is, you, doesn't need to worry about electricity charges, maintenance and other miscellaneous things. Just count the extra money in your account every day.

3. It's very high. I've worked in the same instry

4. There are many cloud computing service platforms on the market now. You only need to purchase the computing power contract and provide the wallet address to start mining to obtain tokens. The operation mode is simple. The more reliable cloud computing platforms on the market are bitmainland's computing power bar, Maya's cloud computing power and other platforms.

5. Basically, you don't need to pay by yourself, that is, you need to remit a deposit in the early stage according to the miner model you choose, but when the service life is up, the deposit will be returned in full, and then you can get the corresponding income according to the Miner you rent.

6. Now a lot of people are investing in cloud computing power, it should be good, but we must choose such a big platform as ANCO computing power in order to ensure the income.. OK, if you need, please feel free to ask.

7. You can access the Paysafecard prepaid card. It's very convenient for many European countries to buy offline. When you pay, you only need to enter a 16 digit string, and you don't need to enter an account number and password. So many European games support it, and now it's one of the largest Payment institutions in Europe; In addition, there are many online bank transfers through sofort, which can be used in many countries such as Germany, Austria, the United Kingdom and the Netherlands. There are also European local payment channels in China. You can find them again

8. 解：前n项和公式为：Sn=na1+n(n-1)d/2 即二次函数形式
故设：Sn= (2n--3) x kn Tn= (4n--3) x kn (k ≠0)
所以 Sn= 2kn^2 --3kn Tn=4kn^2 --3kn
所以：S6= 72k --18k= 64k ，S5= 50k--15k=45k 则 a6=1/2(a3+a9)=S6--S5 =19k 即：a3+a9=38k
T6=144k--18k=126k， T5=100k--15k=85k则b6 =1/2(b5+b7)=1/2(b4+b8)=T6--T5=41k
即：(b5+b7)=(b4+b8)=82k
所以：a9/(b5+b7)+a3/(b4+b8)= a3+a9/(b5+b7) =38k/82k= 19/41
不懂可以继续追问，望采纳，谢谢

9. In my opinion, investment in computing power should be suitable for retail investors and novices. You have no experience in currency speculation. The cost of buying mineral machinery is too high for retail investors, and the money earned is not enough for electricity bills.
