Bitcoin developers are ones which with the aid of proper education, training, research and practical work have helped in improving their skills and knowledge about bitcoin resulting to quality contribution to the bitcoin ecosystem, making it fast and efficient.
It is true, bitcoin developers have being increasing over the years but with recent happenings, don't you think bitcoin need more developers?
Though. In this world, nobody is perfect, and for things to be done perfectly, we need to implement the method of teamwork, so to me, I believe that since with the current adoption of bitcoin, there are still some faults and some things that need improvement in the bitcoin ecosystem, I think if there are more developers, perhaps they will be resolved. But one of the reasons why some developers will not want to work in the Bitcoin ecosystem is that bitcoin is technically large and only cyber knowledge can make them work perfectly in this profession. They need to learn cryptography and some other skills here before they can be able to solve issues in the Bitcoin ecosystem.
With the rapid adoption of bitcoin around the world where by some countries now uses bitcoin as a legal tender, companies and some other stores or shop now also uses bitcoin as a means of payment and concerning creating awareness or educating new users, I think the need for more developers should be considered.
I think this is why the community is open place where everyone can bring up their own idea or create something new that they feel it will make more sense give more freedom financially as the way the currency was created from the first place. So developer can come in and develop something, and showcase their talent, their people that will use it and see if such thing will provide positive results and benefits to the people. But if it will not, they will go against it and warn people to avoid such thing.
