Hey all,
The Wikimedia Foundation does not hold cryptocurrency in Bitcoin. Whilst we do accept bitcoin donations, this is currently done indirectly via BitPay which converts from Bitcoin/Bitcash to Dollars prior to receipt.
This is documented on our Ways to Give page:

Is FoldingCoin still vulnerable to a 51% attack?
It's still highly vulnerable to a 51% attack because there is literally no way to combat the basic principle without giving up on the idea of decentralization.
I don't know anything about FoldingCoin and whether it is more or less
vulnerable to this kind of fraud than other cryptocurrencies.
The only reason some of the larger cryptos don't get affected by this is because there are so many stakeholders that no one can really get enough power together to take over.
Do you think it is reasonable for the Foundation to convert bitcoin to
FoldingCoin as part of its program to source clean electricity?
In a nutshell, no. While Folding@home is a worthwhile project, FoldingCoin is not, and the fact one project is worthwhile should not be taken to men the other has any merit whatsoever.
No serious person should be investing in someone else's cryptocurrency, the underlying technology is free and if you want one, make one. The blockchain is just a software package that anyone can make their own version of as easily as installing a MySQL database. Simple as that.

Hoi, Bitcoin and its ilk rely on an overabundance of energy. In this day and

the speculation of these "currencies" is irresponsible. The best attack
on
this pyramide game is to stay away from it. Thanks, GerardM

What is a 51% attack?
A 51% attack is when a single malicious entity controls >51% of the computing power being used to validate the blockchain of a particular digital currency. Blockchain-based digital currencies rely on a
consensus
of computing participants acting in good faith to verify transactions
and
coin ownership. However, if a single entity controls a majority of the compute power, then it is possible for them to maliciously validate bad transactions to steal, double spend, and otherwise commit fraud using
the
currency.
Smaller digital currencies, with fewer participants acting to maintain their blockchain, are generally more vulnerable to this kind of
attack. A
bad actor can rent a large block of computing power and then use it to attack a small blockchain. Such attacks have been becoming more
common,
though the largest coins (e.g. BTC) are still resistant due to the size
of
their community.

I don't know anything about FoldingCoin and whether it is more or less vulnerable to this kind of fraud than other cryptocurrencies.
However, the 51% attack may just be the death of many smaller alt-coins, unless an effective countermeasure can be developed.

Cryptocurrency. If your first thought isn't "how could a scammer exploit this" you are doing it wrong.
I've thought about that for several hours now, and I'm sure scammers far prefer bitcoin. Folding@Home's lab director is a partner Andreessen Horowitz, so he has certainly had no lack of resources to defend against the possibility, and I am persuaded that the Indiana nonprofit behind FLDC is sincere and acting in good faith at
present.
If the Foundation is hesitant, they might sponsor an audit of either or both, but the Folding@Home project is so established that its article is featured on enwiki.
I have no financial interest in any cryptocurrency, and I never
have,
and I don't have a familial interest with anyone who I am aware has any either.
Best regards, Jim
