Evm compatible - most devs/builders are used to building on Evm networks.
More builders using Eth nativethan anything currently I’d say
Even when Kaspa does release the necessary updates they won’t from my understanding be like say Eth - so builders would need to learn the processes
Smart contracts needed for protocols that are not available on L1 yet
Fully working eco on L1 is still a fair way off from say Eth, Sol, etc.
Obviously the Tocatta HF helped and released a few great additions but it’s far from a completed project mate.
Also even if fully built out, what incentives or marketing if there to bring developers/builders to Kaspa ( this need to be thought about and a plan put in place or it’s all for nothing )
Obviously this is just my take on it mate
