Yes the price might get as low as $1,000 but after this it will be the Moon, so this might be a great time to invest in BTC and some specific altcoins when they reach the bottom
And yes, altcoins will go 5x-10x lower in price in this period... but we all know they will go up with BTC once BTC will start moving again.
My advice: HOLD EVERYTHING YOU HAVE! BUY WHEN BOTTOM SOME EXTRA COINS.
