In the early days of Bitcoin, there was no way to buy or sell the currency except by negotiating directly with another user on forums or IRC channels. If you wanted bitcoins, you either had to mine them yourself or find someone willing to trade. This changed on March 17, 2010, when a user named dwdollar launched BitcoinMarket.com — the first ever Bitcoin exchange.
The idea was simple but revolutionary: provide a marketplace where people could buy and sell bitcoins using PayPal. For the first time, Bitcoin had something resembling a price discovery mechanism. Buyers and sellers could post orders, and the market would determine the exchange rate. In those first weeks, the price of Bitcoin was established at less than a cent — far below even the few dollars per coin it would reach by the end of 2010.
BitcoinMarket.com was primitive by modern standards. There were no order books, no charts, no mobile apps. The site was basically a message board where users posted offers. Disputes were resolved informally. Scams were frequent. But the exchange served a crucial purpose: it proved that Bitcoin had market value, that people were willing to trade real money for it.
The use of PayPal turned out to be the exchange’s Achilles heel. PayPal’s reversible transactions were incompatible with Bitcoin’s irreversible ones. Scammers would buy bitcoins, then reverse their PayPal payments, leaving sellers with nothing. Within a year, BitcoinMarket.com was eclipsed by a new exchange that would handle transactions differently: Mt. Gox, which had just launched in Tokyo.
Though BitcoinMarket.com is largely forgotten today, it occupies a crucial place in crypto history. It was the first time anyone asked the question “What is a bitcoin worth?” — and tried to answer it through a market. Every exchange that followed, from Mt. Gox to Coinbase to Binance, traces its lineage back to that humble message board launched by dwdollar in March 2010.
