Ok, I'll bite.

...will connect the BitTorrent peer-to-peer network and the TRON blockchain network => BitTorrent will start accepting "coins"

a custom token => a new "coin"

an in-client token economy => the "coin" will only be valid for downloading torrents

to address existing limitations => too many leechers, not enough seeders

and open a new borderless economy => will be valid across nation-state boundaries

for exchanging value for computer resources => bandwidth and storage

Translation:

BitTorrent will start accepting a new type of "coin" that will only be valid within the BitTorrent network to allow leechers to pay seeders to download files.
