info 2 Do not invest what you are unable to lose.
Both information seems outdated but yet they are still valid. No matter how long bitcoin has stayed or survived, if it's still in beta version, we should acknowledge that and not say things off record. Unless there's a consensus to do otherwise, it is what it is and may remain like that as along as bitcoin exists.
Information 2 is valid for all kinds of investment, especially for volatile kinds of investments.
