if bitcoin retraces now soon what will happen to alts? will they fall with it or will they rise how will it play out?
At bull market or bear market, If the price of BTC suddenly increase or decrease, all alt coins will crush. Its the fundamental of the market that never changed according to the different maker conditions.
It is important how alt coins will behave after the crush depends on movements of BTC.
I normal after the sudden price changes, money must follow to the alt coins and at coins must increase while BTC is stable or small pries changes at BTC.
By the way, last two months we see that this scenario which mentioned above is not valid anymore. After sudden price changes at BTC, alt coins do not recover themselves as BTC recover. Everyday we see new all-time lows. So everyday making profit from the market become more difficult.
