==Criticism==
===Sync time===
Bitcoin Core is often criticized for being slow in downloading and verifying the Bitcoin transaction database (the [[blockchain]]). The download may be quicker using the [https://bitcointalk.org/index.php?topic=145386.0 bootstrap method]. '''NOTE:''' As of version 0.10.0 it is now slower to download the blockchain via the torrent than it is to download the full blockchain through the P2P client.
===Bandwidth use===
It has also been criticized for "hogging" upload bandwidth when peers connect to download the blockchain (possible only when run with port 8333 accessible to outside connections).
This perceived "issue" has been [https://github.com/bitcoin/bitcoin/issues/273 discussed extensively on GitHub].
Most modern routers support quality-of-service that can be configured to properly share the internet connection across all services, and even deprioritise Bitcoin traffic.
Bitcoin Core includes a script for Linux to configure QoS on an individual host.<ref>https://github.com/bitcoin/bitcoin/tree/master/contrib/qos, Linux QoS bash script</ref>
Windows users can also use third-party software such as [http://seriousbit.com/netbalancer/ Netbalancer] to throttle the application's upload bandwidth and ensure that one has enough upload bandwidth available for regular computer and internet use to be unaffected.
===Lack of multiwallet support; node+wallet tied together===
Wallet management is also cumbersome. Unlike clients such as [[Armory]], [[MultiBit]], [[Electrum]] and others only one wallet at a time is supported, and its location is required to be the same as the blockchain storage, making it [[Securing_your_wallet#Making_a_secure_workspace|difficult to place the wallet on an encrypted drive]]. It is recommended to backup the wallet.dat file every 50 transactions, due to the way Bitcoin Core handles [[Change|change]].
