its a really good documentary , im still quite new to cryptos , even though i looked into bitcoin 8 - 9 years ago , but it was a bit too complicated for me then and i really regret i didnt man it out and try a bit harder , i got as far as down loading a bitcoin wallet but was mystified at the job of downloading the block chain and it just seemed like i would never be synchronized , it turned out getting me synced was the problem :-) and this doc is a great help , thanks for posting
