It will be very difficult to dump the market further(it is possible, but it will be very difficult and dangerous), because the miners are already working at a loss on some coins, like ethereum. Bitcoin almost fell to mining cost price, so, i think, it worth to start to buy now.
exactly, now is the right time to buy lots of bitcoin. although now the price is still low. but according to my analysis personally, in the middle or at the end of the year the price of bitcoin will again grow up
