All the things you have heard and know about Bitcoin are true. If you want to know more about Bitcoin then you must spend more time and know more. The more you are interested in knowing, the more you will know. As the saying goes, there is no end to knowledge and no age to learn. Finally, the last thing I want you to know is that bitcoins cannot be hacked, of course bitcoins can be hacked. If you use your wallet and bitcoins carelessly, you can get hacked anytime. Except if you use bitcoin wallet and bitcoins with security then you won't get hacked.
Hmm, I found one of the above post saying Bitcoin can not be hacked so I ignored to reply to him but you made it correct. well said dear bitcoin can be hacked at any time if your private key is compromised or leaked by someone else. well, I have heard from my elders that learn knowledge until you are not dead. I would say the more knowledge you have should be counted less because knowledge has no limit because it is endless. Many Thanks!
