4. Community size: The scale of the group is what significantly impacts the Bitcoin price or every other crypto. A wide group is signalling that there is strong interest for this coin. Many businesses and individuals use it, and that broad adoption encourages more growth.
5. Ecosystem development: Many cryptos have their issues even the head of it all Bitcoin. Presently scalability is the main challenge of bitcoin, This means the network is unable to deal with the rising amount of transfers that users submit. Many cryptos have their issues too and these issues can cause a decrease in the price of them
I think you can remove this two since "Community Size" is something already part of the "demand" part of demand and supply. We can't really separate them since you are just basically telling another definition for demand. For the ecosystem and development I think this just all go into market speculation, even if there is something new with their development we can't really translate this into an automatic price increase for a cryptocurrency. We have seen it before where project devs even if they worked their ass off on a new development it doesn't translate into any price increase for their projects.
