You assume that early adopters still hold their Bitcoins. A tiny fraction of them might, most of them have sold (and regretted it, me including).
The Bitcoin traders are estimated to a few hundred million, certainly not "a few". Coinbase alone have approximately 56 million accounts.
The market is constantly crashing and reviving, people refusing to take the risk and buy should not complain afterwards for the new "elite" class. You had your chance (multiple times).
