This raspberry pi can handle all the work If the big miners are out?
Anything that can download the blockchain and run as node can do the work, but this is just in theory, we will not expect such to happen because if all miners are not mining and remain only few miners, there will be possibility of 51% attack because the hashrate will significantly reduce to an extent the blockchain may be vulnerable to 51% attack, but I do not expect big miners to leave mining bitcoin, it is not possible. If as a result of the country they are banned not to mine, they will move to another country, also this will be the reason many other miners not in such country will increase their mining power for better opportunities, some people will also join mining. There is nothing that can affect bitcoin mining power to such extent.
Im asking can the Bitcoin Network Still can function normally as usual If the all big miners Will be down?
All the attacks are from the insiders every attacks Hacks are always inside jobs.
Regular Person Can't do nothing.
