All right. I'll start with the first one.
On the subject of instability, the best example I can give is Shopify, which is down 80%. There's real estate as well. Today, interest rates are high. This obviously has an effect on all investments. I started my first business 22 years ago. If there had been a way at that time to see the value of my business every second, I would have found it very unstable, because I would have seen the number of clients change constantly. If I gain one customer, then another two days later, and then lose one after that, that means I'm seeing the value of my business increase by 100%, then decrease by 50% per day.
What happens, when you use blockchain technology or cryptocurrency exchange, is that you see the fluctuation, in real time, of something that has just been created. Previously, when a company went public, it had already been doing business for 5 or 10 years. So when Shopify or even Microsoft went public, obviously you didn't see any instability, even if there were positive or negative fluctuations of 50% or 60%. In the case of cryptocurrencies, their value is displayed from the moment they are created, so it's normal that there is instability.
As for the dangers related to other use cases, as I was telling you, in terms of blockchains or databases — I'm thinking of Neoflow and even health care, for example — a cryptocurrency doesn't necessarily have to be associated with it. So blockchains are extremely secure. It's probably the most secure database in the world. You only have to look at the Bitcoin network, which has a global value of trillions of dollars. If the blockchain could be hacked, you can imagine that this would have happened already. So it's the most secure database in the world, similar to a decentralized accounting ledger.
So, in terms of using blockchain technology in cases where there is no cryptocurrency, in my opinion, no regulation is needed. Moreover, it is one of the most secure technologies at the moment.
