Bitcoin and Altcoins have undergo phasic and non-phasic cycles with each other. It's like when looking at two cars in front both with their left blinkers on. The blinking are out of sync at first and soon they come into sync. Or non-phasic to phasic.

Altcoins and Bitcoins are similar.

Now, in times when Bitcoin crashes, Alts will not be spared. There is no true inverse altcoin to bitcoin.

I go to bitUSD or FIAT during such big corrections.

I don't really hedge the cryptos as there are no real inverse instruments.

I maximize gains by buying at the terminal ends of a,b,c corrections and selling on fifthe waves. Please review my tutorial explaining these:
