This is not true. I used to be a professional market maker in Bitcoin. This year, Bitcoin market is relatively calm in at least half of the time, meaning 12 hours out of a 24-hour day, longer than most established equity market. Under these normal conditions, trading $1m worth of Bitcoin moves the market by less than 0.01%.

Citation needed. Checking the bitfinex order book:

A trade of $10M, or 1250 bitcoins, would move the market by 6%
Maybe pick an exchange that isn't #60 based on transaction volume?
I'd guess you'll lose far more than doing the same with gold, because the market slippage due to lack of liquidity far exceeds the cost of those vaults, banks, and guards.
