unless the price drop too much
it will

no guaranteed that it will fall so much, actually i don't see it falling for that reason

"Every miner should sign the blocks that he solves with his own key. After a miner has created a lot of blocks
over month that get accepted by other miners, new blocks of the same miner deserve more trust than blocks
of new miner"

Miners  who are more trusted could then flood the network with 'bad blocks'. It would only take one bad block for a miner to double spend and receive a lot of bitcoin.

A better idea would be to have a cryptographic miner inaccessibly tied to a biological identity. It could sign blocks, as you described, but because the hardware would be rely on tasks performed by the human body, there would be no risk of forgery.

I describe this in my thesis on building a brain-to-brain, 'proof-of-humanity' blockchain. I haven't yet sent it to cryptographers, but I'm interested in receiving feedback.

what if one accumulate trust just to do bad thing later? there are plenty of cases like this in other "applications"

the network should secure itself(the chain) through a sophisticated bot, the human help should be avoided as much as possible, this how i see it

it could work in the same way as a cash(there are various thing in a money cash that make it different from a false cash money), so with something that identify the real block from the false
