The Bitcoin network is so impressive and it's the best I have ever seen, it produces 67 times more hashes per second than there are grains of sand on Earth. This is so so amazing and incredible. another amazing fact is that in terms of raw operations per second, it is 500 times more powerful than the world's most powerful supercomputer.
Let me believe that this mate is amazed by Bitcoin technological concerns rather than it's economic importance. I believe the economic importance of Bitcoin is worthy of nothing before you can fully call Bitcoin powerful. In fact what gives Bitcoin it's dominance and power is owing to it's high economic features, else the technological part alone would've been just a liability.
Bitcoin is a store of value and an investment opportunity.
It is also a hedge against inflation. Furthermore it's decentralized, transparent and it's not controlled by government.
Bitcoin transaction records are immutable and publicly available on the Blockchain, also in Bitcoin, you're in charge of your finances.
These are the core features that makes Bitcoin much more powerful.
