if with just 10BTC can make you become a millionaire , what about people who own 1000BTC? i think they'll be a quillionaire 
those people will dump long before, because their target is lower than those that have only 10 btc
so those "1k people" will be the "10 btc people" in the future, with the same opportunity for the former
Agree. I think on the way between now and $1M, most of the coins will "change hand", as many will want to take advantage of the new highs and cash out. It all depends on the price of the coins you are holding/hodling...
