<p>I don't know for certain, but I think it would be the Winklevoss Twins, who originally started on the system we now know as Facebook but where shafted by Mark Zuckerberg who made it the phenomenon it is today (making him one of the richest people in the world). &nbsp;Apparently after that whole situation, the twins then got involved in Bitcoin, back when it was worth hardly anything and so now they've made millions.</p>
<p>I think most of the people that made a lot happened to be in the right place and the right time, and believed it would go somewhere... which must have been hard for the first 7 years of Bitcoin's life.</p>

<p>What do you exactly mean with most profitable cryptocurrency investor? The most profitable money wise or percentage wise? Because it's not if you are the richest cryptocurrency investor that means that you also had the highest percentage gain over your carreer. Because it depends on what your starting capital was. If you turn 1000 dollar into 100 000 dollar that's a 10000% gain. If you turn 10 million into 1 billion you also made a 10000% gain.&nbsp;</p>
<p>If you want to know who are the richest, according to forbes these are:</p>
<p>1 Satoshi Nakamoto - 19 billion $</p>
<p>2 Chris larsen - 8 billion $</p>
<p>3 Joseph Lubin - 1 - 5 billion $</p>
<p>4 Changpeng Zhao - 2 billion $</p>
<p>5 Winklevoss twins - 1 billion $</p>
<p>Take note that not all of these people are investors. Some are entrepreneurs or inventors. The richest investors would probably be the Winklevoss twins. But they also had a lot of capital to begin with. &nbsp;The $65m they secured in the facebook lawsuit helped fund their subsequent venture capital projects, including bitcoin.&nbsp;</p>
