Cryptocurrencies are P2P so they can't be truly stopped, just like P2P piracy couldn't be stopped. Centralized exchanges are about as big of a weakness as centralized public torrent sites are, but even that could be changed if the need for decentralized exchanges truly arises. Right now, decentralized exchanges have a big chicken and egg problem (you need sellers to buy, and viceversa). But if the top 10 cryptocurrency exchanges were shut down, the chicken and egg problem would disappear.
