I think there is always a chance that BTC will be worth 0 one day,even Satoshi Nakamoto say "I'm sure that in 20 years there will either be very large transaction volume or no volume".

It is well known thing that banks and other financial institutions do not have a friendly attitude toward BTC and others crypto coins,something like that is a threat for today's system in which they generate huge profits.So you do not have to be surprised when you read such news,it is only FUD and it show that system is in fear of change and losing control.

I think that BTC is show resistance through the years and it is far away from 0.

Yes I personally feel this is the best time to get into bitcoin again....soon will be back ontrack and give high profits in short term investing too.
At present, bitcoin prices are down at $ 6,644. This is a opportunity to buy bitcoin for long-term investors.
But still need to be careful as the downtrend remains. The reason for the bad market may be due to an increase in access bans for international trading sites in China and the number of banks prohibit credit card payments for cryptocurrency
