For Blockchain IT Code development you just need the University degree or the coding skills,

For Blockchain Project Developer, meaining using Blockchain to help in the real world economy, you can do without coding skills but:

you cant just be one, you have to have the skills needed and develop, while knowing what you are doing,

or in other words you have to have an orientation what you are developing this is very rare, especially having a good orientation for a longterm sustainable and good project,

all those scamcoiners have tech skills but they lack skills creating a cryptocurrency that helps people
