See how much you would have made if you bought Bitcoin at a specific date.
Laszlo Hanyecz, an early Bitcoin miner, made the first known purchase using Bitcoin as currency, exchanging 10,000 BTC for two Papa John's pizzas.
This transaction, arranged on the Bitcointalk forum, marked Bitcoin's first use as a medium of exchange in the real world.
The value of the BTC at that time was approximately $41, setting a historical precedent celebrated annually as Bitcoin Pizza Day.
A significant vulnerability in Bitcoin's protocol was discovered, where transaction outputs could overflow, theoretically allowing the creation of an unlimited amount of Bitcoin.
The issue was flagged by the community, prompting immediate attention to secure the network.
Exploiting the vulnerability, an attacker created a transaction generating over 92 billion BTC, far exceeding Bitcoin's intended supply cap.
This exploit led to a swift response from developers who patched the bug and implemented a hard fork, invalidating the fraudulent transaction and restoring security to the network.
This incident remains one of Bitcoin's only major security flaws.
