I am brand new to crypto...Have been studying it for several weeks now. I am about to try my hand and invest in limited way to learn the ropes of trading. So I have Q's as to security: Could I place my wallet or wallets on a USB drive that I have internally encrypted for security and use them that way? Also could add malwarebytes to it.... Could I not do the same thing by just by encrypting a folder on my desktop and placing my wallet or wallets in it? Wouldn't that be close to being a Ledger Nano S?
