1. What does the number of people in the Ethereum contract mean? I know the top speed.
2. The smart contract has been written for a long time
if they can add changes, the description is centralized
the contract is written into the Ethereum smart contract, which is a contradiction sentence
the financial customer service doesn't understand, which is very unreliable

3. Gas & gt; ethestimateGas({ from:ethaccounts [1], to: ethaccounts[2], value:50000000000000 }) 21001 > Ethgasprice 2000000000, as shown above, shows this account [1] = & gt; The transaction of account [2] needs 21001 gas, and the current gasprice is 2000000000. How many gas does it take to send transaction / call contract method in Ethereum
4. Yes, refer to the interaction between contracts. Digital currency exchange platform for example, I am trying to sign a smart contract from another factory contract and then redeploy the address of the new smart contract. However, the address it returns is the transaction hash, not the contract address. I believe this is because when the address is returned, the contract has not been exploited. When I deploy the smart contract with Web3, it seems that it will not output the contract address until the smart contract is deployed
5. As long as you can pay the deposit, choose the right direction.
6. Just like a contract to buy
bitcoin, you can choose, perpetual or delivery.
7. Yes, most coins can be traded in okex.
8. Bitcoin, which is well known to the public, is the classic of ether. You can know that Ethernet classic has done some homework. It is a
blockchain + smart contract platform, and many dapps are developed based on it. Function is similar to our mobile phone system, is the underlying technology, based on this technology can develop many applications and procts, drive the development of the whole instry.
9. Not necessarily, but Ethereum has no upper limit, which is really good
