The governments can only slowdown cryptocurrency revolution but they can't stop it. BTC, LTC are traceable, so you can still track down owner (although it may be extremely difficult in some cases). But with technologies like zero-knowledge proof in ZCash, you have untraceable money. So at some point, when cryptocurrencies hit mainstream, you may see the situation when people start exchange goods and services directly in ZCash or Monero. I just don't see how government can shutdown this. I don't see how governments can crackdown cryptocurrencies completely. So in long term, impact of cryptocurrencies on global economy is inevitable.
