FinFly Explains / Crypto
What Bitcoin is
Bitcoin is an open payment network; BTC is its digital asset. An exchange balance is not the same as controlling your keys.
Price
Supply and demand determine market price. Limited issuance does not guarantee profit.
Before sending
Check the address, network and fee. Back up keys securely; an exchange password is not a wallet key.
