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.
