I'm fairly new to crypto. I have some coins sitting in coinbase but I've been reading that it's not safe to keep coins in a wallet like that or on exchanges for long term holding. I am curious about 'paper wallets' to store my crypto offline, but I don't know how it works or how I can move my crypto to it?
Specifically I'm looking at walletgenerator.net, has anyone used this successfully and is it safe? How does it work? It creates an address (like a wallet?) for me to transfer my crypto into, and it can't be accessed online? How would I be able to see what is in my wallet? Would I need a new paper wallet for each type of coin I hold?
Sorry for being a noob.
