How about this strategy:
(for people who don’t think all alts are a scam)
Bitcoin leads the pack but altcoins RISE and FALL much faster than bitcoin.
So, in theory, if the market is rising it makes more sense to get you mined ZCash and trade it quickly to one or more altcoins that look promising.
And if the market is falling it’s better to buy bitcoin and wait because altcoins will fall faster and when bitcoin hits bottom one can buy more altcoins.
