Having had interest for bitcoin among all altcoin, I tried to imagine if the price of bitcoin is reduced to atleast 80% so that It can be affordable, and before this is done a proper warning is sent to all the users and holders so that they can sell before time to avoid lost on their part and buy back when it is stable and relatively cheap.
The world is now digitalise where induction, orientation and serious campaign about bitcoin is prevailing but the major constraint for adoption is the price which had made old users to benefit from the system. For instance to own a bitcoin in my country is above a million naira. Where will one get this money from as a newbie. Let it not be as if there is no hope for us that are new to the ecosystem.
Why do you want bitcoin to pullback 20%? When you look at the 4 year cycle, no matter what price you bought at, you "are in the money". Furthermore, There will be no warnings about price fluctuations, but you should not be worried about fluctuations if you are a long term holder. Again I point you to the 4 year cycle.....
We just need to buy consistently - and everything will be great in the long run, with or without such big pullbacks.
