But won't it lead to frustration of unconfirmed transaction? Because lmost all nodes have 1 sat/vbyte and that is how it is in their default settings. If someone wants to make less than 1 sat/vbyte as the fee, nodes will reject it but if there is a node that accepts it, it can lead to longer wait before confirmation if the transaction is not dropped out of memory pool, but it can drop out of memory pool.
There are enough nodes that accept below 1 sat/vByte transaction for them to propagate properly and reach the nodes of the leading miners. I have broadcasted such transactions through Mempool.Space and recently via Electrum.
Just like when transaction fees were high, you will have to determine how much to pay and what your approximate waiting time will look like. If you pay the lowest current fee, which is 0.10 sat/vByte, you will wait a long time. Mempool.space currently shows that your transaction would confirm in 18 blocks at best but it can also be much longer than that. On the other hand, if you paid 0.25 sat/vByte right now, the first confirmation seems only 1-2 blocks away.
I also went to their GitHub to know if they have it there, but version 7.1.8 is still only the last version for Android. Only iOS latest release is there.
You are right. There are no .apk files available for download for Android phones.
Just like block 910264, there are 2531 transactions there but there are only four transactions that have fee below 1 sat/bytes which is very small to me.
When that block was mined, there were enough transactions that paid over 1 sat/vByte to fill most of the block. The miner then took only a handful of sub 1 sat/vByte transactions to fill the remaining block space. But there are also miners who still reject these low-paying transactions, so they end up with blocks that are only 20% or 30% full. That makes no sense to me because miners want to make as much as possible. Sub 1 sat/vByte transactions are now a reality. Excluding them is leaving money on the street. It's not a lot, but still why throw it away!?
