just ask yourself how many ppl do own apple shares ? now go and look at the monthly volume traded by the big banks
I do not expect big banks get into btc any time soon. But when it happens, my approach will change.
What would happen then?
Would the price stabilize or become more volatile?
If big banks decide to join the game first they will try to devaluate btc in order to buy cheap (big players always use such strategy). This could be done by rumors or a plan of making btc illegal but not making it illegal actually (they have the tools to make this happen). When the price falls and starts to stabilize then they buy. If devaluation at some point ever begin then keep a close eye in the volume.
