Sputnik: Should cryptocurrencies be banned?
Dr PJ Radcliffe: In theory; it might be good to get rid of it because so many people have lost money and so many crimes are being committed with it.
Practically; it's going to be very hard to do, and I don't know if it's worth trying to ban it now. There's been much publicity that you could lose a lot of money with Bitcoin that people may remember for six months or more.
Dr PJ Radcliffe: The speculative boom has certainly burst. When things are going up in price, people get all excited and pay more and more, and I think that this kind of excitement is over and done with.
There are a couple of problems that people are beginning to realise; there's a war between Bitcoin and Bitcoin cash, that's quite a big conflict there. In fact, Bitcoin has said, if possible, that they'll try and do a fifty-one percent attack against Bitcoin cash.
If you control fifty-one percent of the mining, then you can re-write the blockchain to everybody's disadvantage, and Bitcoin has said they might do that, so that's a bit of a worry.

Sputnik: Assuming any potential bugs were ironed out; could cryptocurrencies replace physical currency in the future?
Dr PJ Radcliffe: One of the problems with Bitcoin is that there's nothing really behind it in terms of value. With the US dollar, the Australian dollar, or the UK pound, there's a government sitting behind it with assets, but with Bitcoin there's nothing, so if people all of a sudden get scared and sell a lot, the price can go down, and because of that volatility, because there's no backing behind it, it doesn't make a lot of sense as a currency.
There are very few places or uses where you can say it's superior to existing financial products. Possibly one is international currency exchange, as there is quite a large fee between converting currencies, which I think is quite excessive.
That's the only case where Bitcoin might be useful. Apart from that, other mechanisms are cheaper, more reliable and faster as well.
