Everything I can read from the Bank of America research note quoted in Inside Bitcoins press release is Positive NEWS:
“According to the analysis, a minimum of $2 billion in inflows would be needed in order to move the Gold market with a single percentile (…) For Bitcoin, however, the researchers speculate that as little as $93 million of a net inflow could be all it takes to push Bitcoin up by 1%.”
According to the same press release, the $2 billion required to shift the gold market with a single percentile varies by about one order of magnitude from the $0,1 billion required for the same impact on the Bitcoin market; the same one order of magnitude that divides the cap market sizes of both Bitcoin and gold.
As a consequence, if (when) the Bitcoin market cap exceeds that of gold, the exposure to cash inflows will be the same for both, equating the efficiency of both as a store of value.
But, given that Bitcoin took 12 years to hit 10% of gold's market cap in 5000 years, all I see is a bright near future: Bitcoin is on the right and fast track to being a "great" store of value... if it hasn't already.
