This distributed ledger which has reached more than 235 gigabytes in size as of Jan 2019, must be downloaded or synchronized before full participation of the client may occur.
Howells grabbed the unwanted hard drive and threw it into a black garbage bag. “Fear and excitement in El Salvador as Bitcoin becomes legal tender”.

But, eventually, the memory of the money he had thrown away overpowered his work ethic. The first time he mined, Howells’s computer was one of only five on the network. He told me, “I know this because when you’re in a Bitcoin network it tells you, on the bottom right, ‘You are connected to x amount of nodes,’ or machines.” He mined at night, off and on, for a couple of months. But the mining took a lot of processing power, causing the laptop to overheat. The computer’s whirring fan began to irritate Hafina, and he decided to stop. The coins had no value at the time, and there was no reason to think that they ever would. “It was an experiment.” The electricity required to keep his computer going had cost him about ten pounds.
