Why do people keep saying BTC is dead?!
Because they don't know what they're talking about. Those people are just handing their bitcoins to someone else who deserves them more.

They do not know what bitcoin that's the point
Whereas we use bitcoin for future money

Yes, bitcoin is not just money more than it, bitcoin is new technology that there are not something like bitcoin before, many people doesn't know about the chance to getting beneficial of bitcoin, so the peoples keep saying bitcoin will be dead, although the fact bitcoin is more growing.
