Hello!
I´m totally new to this and not a computer guy.
So I´m wondering about this cold storage that seems to be the only option. Can I store the wallet on a regular USB stick or some smaller hard drive?
Or does it have to be an offline computer or hardware wallet?
Was going to buy an hardware wallet until I realized that they only work for a few altcoins..
And the blockchain program needs top be on my online computer if I´ve got it right?
