Blockchain technologies are here to stay. Wikipedia does a superb work on describing what a blockchain is.
A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.
Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data.
By design, blockchains are inherently resistant to modification of the data. A blockchain can serve as “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way.”
As you can read, it has nothing to do with money, or bitcoin, or any other cryptocurrency. Bitcoin is just a “way” to apply the blockchain technology, one of the many available.
Probably one of the first, ok, but it’s weird for me to see that now Bitcoin is subject to pure speculation. On the other side, it’s really interesting to watch how a completely unruled market behaves.
Law of supply and demand at work, with no restrictions. Something not that common, nowadays. Only one thing scares me: I see/read about people making debts to invest in bitcoins. People moving all their savings to bitcoin. People that sometimes don’t understand what they’re doing.
At some point, bubble or not, something will happen and some people will lose all its money… Not fun.
Do I have any bitcoin? Yes, I’ve sold some recently and now I’ve around 100€ in bitcoin, something I can afford to lose, if the bubble bursts.
