As you know, the number of confirmations in bitcoin transactions have a direct effect on transaction speed. A transaction with 3 confirmations will be processed faster than the one with 6 confirmations. The process of confirmation is approved by any computer which is on the blockchain network. So, we have a network with a lot of computers and miners but not all of them are always online to confirm transactions. What I want to know is that whether the number of online computers on the network can affect bitcoin transaction speed or not? Does bitcoin transaction speed increase if there are more online computers on the network? Does it mean that bitcoin transaction speed will improve in the future when the number of computers on blockchain network increase?

According to technical articles, blockchain network consists of a chain of blocks that are all connected to each other in a series. So, we should be able to see all transactions that has been done in this network since 2009. In order to see transactions we should have wallet addresses. Is there any way we can find transactions based on the amount of money that has been transferred between senders and receivers? For example, if we could search for all transactions with amounts between 0.001 and 0.01 BTC in a certain period of time. The date of transaction is also an important criteria for searching. If we could search based on amount and date, we could find out in which date the highest or lowest amounts of money has been transferred with blockchain network. Is it possible to download a copy of blockchain from 2009 - 2019 and search for transactions in it?
