Greetings and thank you for this reply.
In fact I really want to stay on Hive for this, Hive helps me alot, so I want to remain here. Fidelity, you see what I mean ? :) Important thing for me.
Some tell me I should use json to reach my goal... And I will try it unless someone has also ideas to submit. I hope I will be able cause it' slonglong time I didn't code and never really on blockchain
