What exactly are you waiting for when you “wait for 6 confirmations”?
Different blockchains have different block times and consensus mechanisms, so there’s no fixed standard for how many confirmations are considered safe.
Transactions that haven’t been included in a block wait in the mempool. At this point, they have zero confirmations and could be pushed out of the transaction pool at any time or remain stuck indefinitely.
Practical knowledge may seem useless in everyday life, but you realize its value when you run into trouble.
Be extra skeptical of claims promising high returns.

I get things wrong too, so use your own judgment.
