From the Law of Unintended Consequences:
Endurance couch-surfer and WikiLeaker-in-chief Julian Assange has thanked US authorities for the banking blockade that made it hard to donate fiat currencies to his organisation, because it inadvertently enriched the organisation.
The blockade first appeared in 2010, after the United States expressed its ire at WikiLeaks' publication of diplomatic cables. Not long afterwards, Mastercard and Visa stopped processing donations sent to the site.
WikiLeaks sued and won against Visa, but the blockade persisted. The organisation therefore sought alternative funding including Bitcoin.
Which brings us to an Assange Tweet from Sunday, as follows.
My deepest thanks to the US government, Senator McCain and Senator Lieberman for pushing Visa, MasterCard, Payal, AmEx, Mooneybookers, et al, into erecting an illegal banking blockade against @WikiLeaks starting in 2010. It caused us to invest in Bitcoin -- with > 50000% return. pic.twitter.com/9i8D69yxLC

According to Wikipedia, [wikipedia.org] in Feb 2011 (the first given date where I'm sure that it is after the mentioned ban), 1 BTC = $1. The lowest given value in September 2017 is $2900. This is a factor of 2900.
Now a >50 000% win means a factor >500 (well actually >501), which is considerably lower. But then, the donation were surely coming in not only in 2010, but also in the following years. Therefore parts of the bitcoins they got went only through part of the value gain. Therefore the factor of roughly 500 seems plausible to me.
