He's more of sharing his knowledge and I cannot see anything wrong with that. Maybe these are the things that made him understand Bitcoin more, we cannot take the credit out of him if that's the case simply because this topic is subjective. Of course majority if not all, are aware of these things but why do people still are having negative impressions towards this industry in general? Because they lacking the emphasis on simple things like its concept.
There's nothing wrong for someone to share his knowledge, but it's pointless.
He didn't share many or new thing that will make people to learn about it and he didn't ask any question, so... it's like something that shouldn't be discussed at all. This thread usually will be locked by moderators.
Alot of people will say this information is not new to anyone yet many keep falling victim of scam and wrong investment decisions. I believe those who have been victims of bitcoin scam were fully aware that hackers and scammers actually exist but were still taken unaware when it finally happened. If constant reminders on the need to protect our bitcoins and take security tips seriously will help people stay safe, then it should continue so everyone would be at alert. With the way everyone keeps talking about the safety of our coins, if there's anyone that will see or hear about all this and still lose his/her coins out of greed or carelessness, such a person is not really serious about investing.
Because they're someone who don't care with anything until something finally happened to them, but some of them will give up and avoid to invest in Bitcoin since they have trauma. We only need to wait Binance get hacked and their SAFU can't cover the losses.
