More use cases, bigger market, better stability yes ... the thing is HBD is still struguling to prove itself to Hivers as well, who are willing to use it and suport it even at bigger risk then some other options. The native community is still a decent market, and I bet if there is more confidence in hbd, we would see 20M to 50M in HBD in savings, unlike 1 to 2M now ....
Have you seen terra.... the concept is very similar to hive-hbd, just there luna-ust .... instant conversions, with some aditinal infrastructure etc...
