Deepceleron, thanks for answer and for pointing out flaws in my statements.
First of all, FUD, when used as an adjective for virus,malware,etc means Fully undetectable (FUD). I'm not misusing words i heard somehwere, i just didn't know the acronym also stands for "Fear, uncertainty and doubt" too. It seems it is indeed more frequently used as "Fear, uncertainty and doubt", so it was my mistake for not pointing out what i mean by FUD, thus creating this confusion.
Secondly, yeah, the 51% attack was about hashrate, not about bitcoin amount. I didn't know that, thanks for pointing it out
So, the only thing you can do by modifying the software and stealing the bitcoins is to create more panic and to reduce the trust level of the cryptocurrency, if you chose to just bribe the developer and introduce a malicios code into the software.
Yes, by "unknown entity" i mean bankers and their slaves, governments.That's what i don't understand. Why are they only discouraging the use of bitcoins ? I mean there's always a country that will not collaborate with US government and/or their slaves, the European Union. Someone can open the business in a such country, thus making all the bankers and governments efforts futile. Why aren't they just building more supercomputers and take over the network ? I've read the actual bitcoin hashrate is bigger than the hashrate of all supercomputers, if they chosed to mine. But what stops the bankers buy/build supercomputers or buy ASICS ? I mean, discouraging people to use bitcoin may or may not be successful, but buying a huge amount of asics would be a 100% success if they really wanted to do a 51% attack. Money aint a problem for them anyway since they control the money printing machines... They would basically give away colored paper and succeed destroying any cryptocurrency this way. Why aren't they doing that already, if that's the purpose ? That's what i'm trying to understand.
