I recommended online wallets for those just starting crypto currency. Cold wallets are really expensive. An external storage source costs almost 300-350 dollars as of now.
I also mentioned that's if you actually read the post that overall cold wallets are better but " for a beginner it's advisable you start with online wallets, later on if you wish to diversify your assets you could purchase a cold wallet"
Theres other wallet that will make newbie money safe without the use of cold storage for starter. Electrum is the most popular non custodial wallet that is perfect for newbie. The hot wallet example that you choose is just not good since they are all custodial wallet which doesnt have privacy or full control to the wallet. I agree that cold storage is too expensive for beginners but it is good to invest first on the safety of there storage before they start buying there first Bitcoin.
Now from your second reply I can see you're against the Altcoin idea. Yes it's a risk but isn't that all crypto is all about "sometimes you win, sometimes you lose".
You are right though, anyone venturing into Altcoins should start up with a small amount just incase.
You should focus on Bitcoin alone since your thread title states Bitcoin for Beginner. Adding altcoin will just add risk to newbie due to its worst volatility that might cause heavy loss to them. You should consider the safety as top priority when your aim is to give an advice for newbie like you.
