'I lost money with Mt.Gox'

Mt.Gox's instability was apparent to Landon King right from the start.

When he began dabbling in bitcoins in mid-2012, the exchange was his go-to website to sell the bitcoins he mined from this computer.

But anytime there was a tiny spike in trading activity, the website would slow down. If prices changed too quickly, Mt.Gox would just go offline. The final straw for King came when U.S. government agents accused Mt.Gox of lying on bank statements and seized $5 million from its accounts at financial institutions.

"There were other exchanges that operate in the U.S., and the government didn't go after them," King told himself. "So, I knew if the government was targeting a specific exchange, they were doing something shady. That turned me off."

In February last year, he moved over to CampBX, an exchange based in Alpharetta, Ga. He keeps his remaining three bitcoins there today.
