I think it was pretty much proven the other day that there isn't some conspiracy by banks and governments to destroy Bitcoin, considering a handful of testers spammed the network and brought it to a standstill of processing transactions for 8 hours at the cost of approximately $5000 in transaction fees (which is nothing).


If a bank or government really wanted to destroy Bitcoin, they could easily do so by clogging the network for days or weeks by spamming transactions all day to fill blocks, and considering they have not done so, they clearly don't consider it a threat.
