There are many different opinions about Bitcoin, this is my own understanding of BTC:

B: Belief, only the people who have the Belief of freedom and decentralization believe BTC will dominate the future.

T: Trust, the people who have trust in BTC keep the whole BTC network.

C: Consensus, the people who have belief and trust in BTC arrive the consensus without any doubt.

This is my brief understanding of BTC.
