How long does a bitcoin Flasher stay active?
Could you elaborate on the duration of activity for a Bitcoin Flasher? I've heard of these flash transactions, where bitcoins are sent momentarily for verification purposes and then often reversed, but I'm unclear on how long these flashers remain visible or active within the blockchain. Do they last for mere seconds, minutes, or is there a variable factor that determines their lifespan? Given the volatile nature of cryptocurrency transactions, I'm particularly interested in understanding the fleeting lifespan of these Flashers and how they might impact the overall security and integrity of the Bitcoin network.
