An unconfirmed UTXO is the output of a transaction that is still in the memory pool (i.e. not yet confirmed). To prevent DoS attacks on node memory pools, nodes set additional restrictions on transactions that use unconfirmed UTXOs. This means that you cannot guarantee that unconfirmed UTXO will be used at any time. For example, until the first transaction (tx0) is confirmed, the wallet may not be able to propagation of the second transaction shown below (tx1)
Bitcoin's average unconfirmed transaction this week rose 219.86 percent. As of May 3, 2020, the average number of unconfirmed transactions in Bitcoin over 7 days was 1168, up 219.86 percent month-on-month

We note that due to the use of splits and side chains, high volumes can be supported in a short period of time. This fact stems from the idea that if a user buys Dogecoin using Litecoin (within the framework of the world), the transaction will only communicate between the Dogecoin and Litecoin sidechains without affecting performance, such as Bitcoin or Ethernet sidechains.

Dog coin DOGecoin was born on December 12, 2013 by Australian brand and marketing expert Jackson Palmer and programmer Palmer in Portland, Oregon. Dogecoin is based on the Scrypt algorithm, the transaction process is more convenient than Bitcoin, it only takes 1 minute to confirm, BTC takes an hour, LTC takes more than ten minutes, and the number of dogs is more convenient for the public's psychological needs.
Unconfirmed transaction limit refers to the limit on the number of transfers of an unconfirmed transaction, the previous trading limit is 25, meaning that an unconfirmed transaction can only be transferred 25 times in a 10-minute period, the number of transactions will not be packaged into the block. In August, the team promised to donate 1,000 BCH to BCH developers, but only if BCH's development team lifted or expanded the trading limit.

Unconfirmed transaction volumes are almost half of the record highs at the end of 2017, according to the website.
When you initiate a Bitcoin transfer, you need to broadcast the transaction to the entire network, and when the mining node receives the transaction, place it in a local memory pool for some basic verification, such as whether the bitcoin spent on the transaction is an unspent transaction. If the validation is successful, it is placed in the Unconfirmed Transaction Pool, waiting to be packaged, and if the validation fails, the transaction is marked as Invalid Transaction and will not be packaged. In other words, mining nodes need to validate each transaction in a timely manner and update their "unconfirmed trading pools" while matching their computing power. When a node grabs the bookkeeping rights, it draws nearly a thousand "unconfirmed transactions" from the Unconfirmed Trading Pool for packaging. Sometimes our transactions cannot be packaged in a timely manner because there are too many transactions in the Unconfirmed Trading Pool and the number of transactions that can be recorded per block is limited.

The so-called 25 unconfirmed transaction limits mean that an unconfirmed transaction can only be transferred 25 times in a row for a maximum of 10 minutes, and the number of trades added will not be packaged into the block. For example, you receive a second-to-account 0 confirmation payment, and then immediately send it out in a zero-confirmation manner, and so on, only 25 consecutive operations.
