Help me with most secure/anon wallet possible

self.Monero13d ago
What is the most secure and anonymous wallet i could setup if i want to hold monero 20+ years? I saw some guides with tails, but are there more secure OS? Are there any 100% tor+vpn or I2p things i could use? Should i buy a seperate pc and only use it with public wifi? Whats the most extreme anon possible? Nothing is to unrealistic!! Any suggestions? Best regards Edit: what if i setup an auto transaction with one wallet to a ledger?
