-Reduce Traffic
-==============
-
-Some node operators need to deal with bandwith caps imposed by their ISPs.
-
-By default, bitcoin-core allows up to 125 connections to different peers, 8 of
-which are outbound. You can therefore, have at most 117 inbound connections.
-
-The default settings can result in relatively significant traffic consumption.
-
-Ways to reduce traffic:
-
-## 1. Use `-maxuploadtarget=<MiB per day>`
-
-A major component of the traffic is caused by serving historic blocks to other nodes
-during the initial blocks download phase (syncing up a new node).
-This option can be specified in MiB per day and is turned off by default.
-This is *not* a hard limit; only a threshold to minimize the outbound
-traffic. When the limit is about to be reached, the uploaded data is cut by no
-longer serving historic blocks (blocks older than one week).
-Keep in mind that new nodes require other nodes that are willing to serve
-historic blocks. **The recommended minimum is 144 blocks per day (max. 144MB
-per day)**
-
-## 2. Disable "listening" (`-listen=0`)
-
-Disabling listening will result in fewer nodes connected (remember the maximum of 8
-outbound peers). Fewer nodes will result in less traffic usage as you are relaying
-blocks and transactions to fewer nodes.
-
-## 3. Reduce maximum connections (`-maxconnections=<num>`)
-
-Reducing the maximum connected nodes to a miniumum could be desirable if traffic
-limits are tiny. Keep in mind that bitcoin's trustless model works best if you are
-connected to a handful of nodes.
