i don't think it will be worth to buy and hold if the price falls upto 1$ because there will no miner avalible in the network who can bear that much loss per block andits totally insane if anyone keep mining at that rate
Then why people buy alcoins and hold them? and altcoins also have miners, but why everybody screaming here so badly.
bitcoin price will never drop to 1$. and if drop by chance then bitcoin will still survive I am sure.
You think bitcoin will still survive if ever by chance the price drop to $1? Why it didn't sustain support to $300, $200 or $100 and really falls back to $1?
If bitcoin price will reached $1, bitcoin is a fail one and that's it. No way the price will reached $1 without "big factors" as main reasons.
