That depends on your system.  It's possible there is no reason not to
do that on your system.  The main reason would be if you have other
processes that may need to run services on predefined ports in that
range.  E.g., if your machine is dedicated to Tor, then you may not
experience any problems with a setting of 1024--65535 for dynamic port
allocations.  You can check with netstat or similar, then experiment
as desired.

The IANA theoretically registers up to port 49151, with 0--1023 being
the Well Known ports and 1024--49151 being the Registered Ports; in
practice this is probably too conservative.
