This has been posted several times here on bitcointalk about the "Not your keys, not your coins." But it's actually good that it's been posted multiple times as a reminder or heads-up for those who are not aware of it.
And yes that very important advice for newbies in cryptocurrency because once an exchange got hack you don;t have any control of that coins you hold from that exchange.
Let me just add this thread here. It's a list of exchanges that have been hacked since 2011.
List of Hacked Exchanges, since 2011:I would like to share this list of hacked exchanges, after viewing the data, consider how and where you store your Bitcoins.
Several types of scams appear in different sources of news, theft or loss of BTC at the individual level.
I prefer to focus on the hacking of exchanges which is what affects us all, but due to the importance of some Bitcoin thefts outside the exchanges, I will include the most important.
If someone wants to publish their personal experience with any of these unpleasant situations, feel free to do so.
Since 2011 have stolen millions of dollars from exchanges, account theft, security breaches, phishing, some recovered others filed for bankruptcy. The solution adopted by governments to improve security is to implement more stringent and regulatory policies.
- This is a list exchanges hacked 2011/2018,
I hope I do not have to update this year.
- 2019 has been worse than the previous year.
2020 I have updated some data and renewed the presentation of the incidents of the exchanges, I have more references obtained from several sources, once contrasted with mine they give a wider result of exchanges that have suffered some type of attack, so the presentation is annual to have a more specific vision of each year.
The sources are basically online portals and social networks that warn about hacked exchange, once verified it is included in the corresponding list of the year.
"Not your keys, Not your Bitcoin"
My best advice for anyone getting into cryptocurrency: don’t be like me. I tend to gamble what I earn in crypto so don’t do the same. Don’t gamble your crypto.
