This explanation is actually pretty close to the reality. I mean why would wall street really be giving them real bitcoins if they already have such ways of luring people with digital certification. Its truly intriguing how they illustrate people about the owing of physical bullions. When it will come to the bitcoin then they will surely have some boded digital platforms via which they will be given bitcoins but not the real one, just the illusion of same as OP stated.

This will never ever create any real demand about the bitcoin. Because for demand to get hyped, actual bitcoin must be bought from the circulation. :-)

So yeah, it could be the case that Wall Street will never be able to hype this market at all.

If there comes any pseudo marketing due to the fact that Wall Street being entering into market, then there will be smaller portion of population which will go and buy bitcoin in the hope that they will see it hiking one day. But without that its just hope.
