will really the bitcoin and all alts go like last December..? as we can see 10X down every coin when compared to december-2017 price..
No one can say that it will hit like last December last year. Its almost been a month and the price of bitcoin is still stable at 7k and even if it dumps or pump it doesn't go down to 6k to 8k bracket in the last and current month. All altcoin is still bleeding for now but all we can do is endure this bearish months and hodl till the market moves again.
you don't
have to endure anything. you can always take actions and make the best out of a bad situation (or at least a situation that you consider bad).
during a bear market you still can make profit. the common way is to short everything that is falling like shorting altcoins. the other way is to trade the dead cat bounces meaning you buy the shitcoin after it has bled a lot and is about to jump a little then dump it fast after the jump. and finally you can always trade coins that are pumping and we know there is never a shortage of them.
