Do you think its more safe/secured to have all of your BTC/LTC coins in physical than in digital with all those mess and hacked with exchangers?
Physical BTC and LTC coins are nothing more than very fancy and expensive paper wallets. If you are looking for security, then a simple paper wallet is a better option. It is more secure because you don't have to trust someone with your private key, and it is a lot cheaper.
Physical BTC and LTC are great for collecting though. I have several.
