Raphael Nicolle is the founder of Bitfinex. Before that he had an interesting path.
By day a helpdesk technician, during his free time Raphael became active under the account ‘unclescrooge‘ on BitcoinTalk. From this account he makes some interesting posts, including occasional climate change denialism, saying he would invest in illegal businesses, and at least one joke about underage prostitution to make bitcoin. First he got into pyramid schemes, schemes that were not legally registered, and then he got really into pyramid schemes, and then he started defending a pyramid scheme scammer (repeatedly), and then he lost all the bitcoins he gave that scammer.
Shortly after this, Raphael decides he will start his own OTC desk and his own lending program. People will lend him Bitcoin and he will guarantee them a 2% return per week. To make this money he said he would be performing arbitrage, which he described as ‘buy low and sell high’. (Astute readers will note that this at best an extraordinarily simplified definition of what arbitrage is.) This program appears to not have taken off, perhaps due to questions from other forum members about his advocacy for pyramid schemes in the past. The text of the post was later deleted.
After this Bitfinex launched! (Though Raphy could be found still trying to do what look like OTC trades.) Bitfinex was a brand new ‘Meta-Exchange’ that would allow people to trade at either Mt. Gox or at Bitstamp through the BitFinex interface. They also had their own exchange that was based on stolen Bitcoinica code. Bitcoinica was an exchange that was rife with security issues that had recently shut down. The unique feature for Bitfinex that made it attractive (besides the ability to aggregate liquidity across multiple exchanges) was the fact that they had margin and lending integrated into the platform. However, the fact that it was built on stolen code with a multitude of issues in the early months. However, eventually they started to even out. However, there were still some interesting posts including at one point Raphael even made sure to point out that his exchange was a bucket shop. (This was a fact that Vitalik Buterin had warned about in Bitcoin Magazine.)
Raphael gradually took a less and less public role in Bitfinex until (according to his LinkedIn) left his role as CTO the same month that the Bitfinex hot wallet was hacked. He is now interested in anti-aging and looking for an executive producer (he should get in touch with the chairman of Deltec).
