I want to short it but I've no idea how much % of my roll I should short to avoid getting margin called and when to begin the shorting position. According to armstrong the gold incoming crash is coming the week of the 10 of august right ? So Maybe we all should the 9th of august before opening our positions ?

@TPTB: when you say "The higher it goes, the less margin you need to short it and not get a margin call due to volatility to the upside, before the implosion. Another gift from perma-bull-tards." is it because right now btc has only 10% upside max (315/288) ?
