There is no compelling argument here. BTC will be over $25K because there are only 300K wallets? No. BTC will be over $25K if it remains stable, if it isn't replaced by a better alternative (Monero, ZCash, etc.), if it still is the easiest way to move fiat into and out of the crypto ecosystem (still this biggest barrier to use for novices). One could make the argument that it won't win simply because there won't be enough BTC even in fractional shares. But until I see otherwise, I simply wouldn't bet against it yet.
