It is the same question why Bitcoin values so much while other PoW coins do only have a market cap of 1 million.
IOTA has gained a lot of attention in industries and business since its inception. A lot of big companies (Innogy, Bosch, Samsung to name only three) are associated with IOTA (if they're really involved into IOTA is a another quesiton). Also a lot of well-known advisors joined IOTA Foundation. So it is a completely different situation to Byteball. You can not compare both, maybe technology-wise but not marketcap-wise.
why iota marketcap so high?
and same technology byteball marketcap is so low???
I think this is because IOTA got large amount of money from big investors, anyway I guess that these large investors wil see the huge potential of Byteball as well....sooner or later
