Sorry, but no.
Anarcho-syndicalism = workers control the means of production. You work in a factory - you control directly the production process, you participate directly in the decision making and you OWN the fruit of your labour.
Communism = social ownership of means of production. It might seem similar, but its not at all - as a worker you do not "own" the means of production nor the fruits of your labour in a communist system, the "society" does, which basically means that the State owns them. That's why Bakunin said communism was going to be "the biggest lie of the Century", and it even said communism was just a form of "state capitalism", as the worker did not control the means of production nor the fruit of his labour. An exception would be Pannekoek's council communism, which was totally opposed to russian bolshevism, and was in many ways much closer to Kropotkin's and Bakunnin's anarcho-communism.
And again: Bitcoin is just a currency, and it has no political sign - but saying is "anarcho-syndicalist" is simply wrong. Most of original anarchists (or "left" anarchists, as some would say, especially in the US) wouldn't even use money as we know it (an exception would be Proudhon's mutualism), in fact during the most relevant anarcho-syndicalist experience in history (Aragón, Spain: 1930-1938) the "Peseta" of the Spanish Republica was not used at all. They had no currency nor legal tender, they just seldomly issued their own "money" which were just vouchers or IOU's with very specific uses. And BTW: anarcho-syndicalism is just a WAY or STRATEGY to reach "anarchy", or "anarcho-communism" or "libertarian communism", as many US folks like to name them to distinguish them from their very own, ill-named "anarcho-capitalism")
Fascinating experience BTW (the one in Aragón), it was a pity that both the spanish fascists and the KPSS (Russian communists) joined forced to crush what could have been one of the most relevant and game-changing revolutions in Europe's history.
Sorry of the OT, folks.
quite exactly, and fuck OT, everyone must have watched this at least once:
