No. Bitcoin is growing and getting more important.
It's not just bitcoin. The issue is that the global banking and payments system is fundamentally broken. Bitcoin is merely one part of general set of financial technologies that will reshape the banking system.
People focus so much on what the price of bitcoin is that they don't look at *how* bitcoin is traded. Bitcoin is quite interesting because it is the first asset whose trading/exchange infrastructure was created from a clean sheet, and so you have things like 24/7 trading, multiple exchanges, and direct trading with counterparties, that are going to eventually be used to trade everything else.
