im not clear on how exactly paper wallets are practical. if i want to invest in multiple currencies i have couple of choices: i can keep my coins on exchanges which is unsafe but lets me respond to the market very quickly, i can download and sync a wallet to my machine or i can go for a paper wallet. but how exactly does that last option work? how come
https://walletgenerator.net/ can give me a wallet for almost every coin there is, i'm not that much into technical apsects, but they cannot possibly all have the same algorithms. but even if the site is legit and i get my paper wallet for some random coin, how do i later check if the money is there?
TL DR: how do i check a balance of my paper wallet for a random coin (not BTC, LTC or ETH you know what i mean)
