There are plenty of Byteball users. They're holding through the distribution, while the new Bitcoin holders getting involved makes the market cap increase eventually, along with the incentive to buy (new bytes in each distribution).
Market cap is still low for a coin with such great potential. Unfortunately, it'll probably be affected by the collapse of Ethereum.
