Yes I think it is very important now as the majority of the hash power will be switched to the 2x chain. We need to show support for the core and our true bitcoin, we cannot be threatened by the miners to turn off the power from the main chain. If we will ignore 2x they will just come back to the real bitcoin, people should panic, we don't need that 80% of power. The difficulty will be adjusted after some time and everything will go back to normal.
Of course!
The TRUE Bitcoin is the only REAL, TRUE money!
And if you control your private keys it IS indeed your only REAL money!!
And your real FREEDOM in this (to a very large extent) material would!
So I'm absolutely sure that running Bitcoin Core Full node, donating those 200 Gb free hdd space and some other tiny hardware donations - all that is just nothing compared to the Bitcoin's true value and prospects!!
