not discrediting devvelopers.. not at all. a true coder .. one who designed something new.. ie: bismuth the python pure block chain, or NEM , or IOTA... that is a crucial developer. but the drive of the project.. thats the team or community...this guy said it best just a min ago
simple explained ..
a Developer doesnt need to be able reading code ...
he need to know when the bill has to be paid
and which persons from his team does which job.
thats all.
nowadays developers are hired guns on upwork or peopleperhour.. trust me been hired.. but if the project is to be a success you will need a mix of honest and unscrupulous team members along with a large community that bought into the teams pitch
