At which price do you think bitcoin will not be able to recover from? There is strong support at $3500 but is now at risk of being breached.
Is $3000 the low point after which there is limited chances of it returning to the glory days?
It all depends on the how the community show support on this idea. Seeing how more and more people become so engage with it, we can expect recovery and "glory day" in the near future. Just continue to buy and hold and expect sudden changes on price from time to time. Get a secure wallet like electrum or Holder and decide to do long term investment.
