i've opted for a chain, other then loose with a probability that he'll ran

i've got him for 2 weeks now, how he loves to bite my fingers and specially my bandages COVERING my wounds lol
he's not into this chain deal, but i cannot afford, emocionaly, to loose him. and his book bitting is not good at all, since i love reading lol also he tries to "kill" my cockatiel! i need some advice and support. i'm a very pacient person and calm, but this finger killer is starting to cross my limit, cause i cant go to work with 1000 wounds in my fingers everyday lol someone might think i'm being abused

atm i got the end of the chain to minimalize any damage he might try to do to himself, also the fall is not as bad. altho when i try to help him, he bites me, but if i pet him (massage/scratch his head) , when he's on my lap, he doesnt try to fly away.

massaging atm, small pupils beak grinding

Should i get him a massive cage? continue to pick up my half eaten books and clean his poo? or continue with the chain "training"?
