The Winklevoss twins have a track record of betting on the wrong horse.
What were those wrong horses?
They trusted Zuckerberg to code their social network ConnectU, he betrayed them and ran away with the idea: fail.
They invested in BitInstant but it went bust as the founder got prosecuted for money laundering: fail.
They are starting an official bitcoin exchange but it's already too late because CoinBase has the first mover advantage and backing from NYSE: fail.
They invested millions over millions in Bitcoin without realizing that it is crippled by technical limitations and already earmarked for replacement by newer and better technology: fail.
The only mistake they made was to trust Zuckerberg when they were teensgers imo
They have amassed a fortune already, more money than most people will ever see in their dreams
1.2 million Facebook shares - win
1% of the total btc - win
Their own regulated exchange - win
First btc etf (if approved) - win
Made money from bitinstant but avoided the legal issues unlike Charlie - win
They also have tens of millions of dollars in cash if not hundreds so even if everything imploded tomorrow they would be fine - win
Seem to be doing OK for a couple of young guys.... But I'm sure you could do it better, right?
