I don't think it will be a problem if we hold coins in btc, because one day the price will certainly rise again, it's just that we have to mentally prepare for it
That must be the holding strategy every bitcoiner is already following; when it comes about bitcoin investments then probably we do not have to struggle for innovating any new strategy but we can simply go for holding strategy by believing into the future of bitcoins.
you just need to wait for the right time and bull run to cash your coins.
For figuring out the right time we must need some strategy otherwise we might be infinitely waiting for cashing out. Most people are going for cashing out based on their requirements and not based on the price levels of bitcoin still I believe they are good to go with that kind of strategy.
