BTC prices are falling continously. Investors in the waking should alert themselves and try to minimise losses by booking profit . If this trend continue for another six months perhaps the present prices will look like a nighmare and it will be late ,moreover the predictions of lower level becoming true .If it is negative view or advise to follow ?
It all depends on what percentage of your money you have invested and how much you can need them (how long you can handle without them). Cryptocurrencies are unpredictable, but nobody expects a price drop of over 90% to last long.
