+Part 3
+Frequently asked questions
+
+00:06.819 --> 00:09.495
+Why won't something else replace Bitcoin?
+
+00:10.694 --> 00:16.285
+In order for something to replace Bitcoin for saving, it would need to
+provide similar and even better properties. While some "cryptos" are
+
+00:16.485 --> 00:22.075
+also easy
+to transport and scarce, none of them have the level of decentralisation of
+Bitcoin, and that means their rules could change when
+
+00:22.275 --> 00:27.865
+under attack.
+
+00:28.066 --> 00:35.626
+The decentralisation of Bitcoin goes beyond the mere technical and
+organisational. There is also a culture of decentralisation, which acts
+
+00:35.826 --> 00:43.385
+against
+attempts to centralise. There could be something else in the future which is
+better than Bitcoin, but as time goes on it is less
+
+00:43.586 --> 00:51.145
+and less likely. It is less
+likely now than it was five years ago, for example.
+
+00:52.940 --> 00:58.291
+If Bitcoin is so secure, why are there so many reports about people losing
+their money?
+
+00:59.492 --> 01:07.877
+In order to benefit from Bitcoin security, you need to follow the five
+principles of Bitcoin mentioned in an earlier video. Usually, when
+
+01:08.077 --> 01:16.462
+you hear
+about Bitcoins being stolen, the people involved violated principle number two:
+not your keys, not your coins. They entrusted
+
+01:16.662 --> 01:25.047
+their keys to someone who doesn't
+know what they are doing, they left it in an unsecured computer, or their keys
+got damaged beyond repair.
+
+01:25.247 --> 01:33.633
+It's similar to someone putting a massive lock on
+their house door, but then leaving the lock open when leaving the house.
+
+01:35.380 --> 01:40.924
+If Bitcoin consumes a lot of elecricity, do I have to worry about my
+elecrticity bill?
+
+01:42.124 --> 01:50.539
+When Bitcoin was originally launched in early 2009, there was only one software
+doing all the work. Gradually, specialised software
+
+01:50.739 --> 01:59.154
+developed for the
+individual activities involved in the network. The, nodes, verify the ledger
+and enforce the rules. The, wallets, keep
+
+01:59.354 --> 02:07.770
+your private keys secure and initiate
+transfers on your behalf. And finally, miners, which consume elecricity and
+provide security for
+
+02:07.970 --> 02:16.385
+Bitcoin. In the meantime, mining is a business like any
+other. Miners run in data centers and in special containers which can move to
+
+02:16.585 --> 02:25.001
+wherever cheap energy is available.
