That 'before it will rise again' is a huge assumption of epic proportions...
It is extremely unlikely it will go up again, next generation coins are taking over. The bitcoin economy is slowly collapsing but will soon accelerate.
I'm a layman in economics, but the way I see it, crypto currencies are of extreme value, and in the long term, become deflationary. Therefore, the only way of one of them becoming extinct is when it's replaced by another. And if they don't become extinct, they will become deflationary and at least at that time, the price will certainly rise indefinitely
According to you, btc is being replaced by next gen coins, what are those coins? Can you give examples of some of them? Why do you think they have the potential to beat bitcoin?
There are few alternatives out there, and they are often summarized as 'Crypto 2.0'. Bitcoin itself is rather ancient by know, and there are more sophisticated ideas out there. Take NXT, or the ambitious Ripple network with its XRP. I'm not that much into NXT, but what gives NXT a headstart on Bitcoin is the simple fact that there actually is development going on there. If you read on about NXT, you'll notice that it is much more than Bitcoin will ever be at this point.
Also, I consider the mining 'problem' to be one of the fundamental flaws to Bitcoin, as it causes massive inflation in the run up period. A certain degree of centralisation is reguired, something the Bitcoin 'Bilderbergers' have seem to noticed. More ideas and business plans and less foolish idealism. I dare to say that idealists rather succeed in building anything of value, as they tend to have a really warped vision on how reality works.
Ripple is something you will have to read up on: it is not really easy to explain in a few sentences. I consider Ripple to be the most advanced thing out there, mostly because it is centralised and run like a business. This however might mean that the holders of XRP will not see any jumps to the moon, but then again, if Ripple succeeds to become succesfull in a niche market alone it will likely reflect on the value of XRP in such a manner that it dwarfs regular ROI's.
About the 'value' of cryptocurrencies: I consider most of them, especially Bitcoin, to be wildly overpriced for something that got almost no real world use. Probably some Bitcoin fanatic will get out of the woodworks and attack me for it, talking about 'ever increasing adoption', but the truth of the matter is that almost NO single Bitcoiner uses Bitcoin to purchase things. It is a speculative vehicle that has gone through a massive bubble phase. It will highly probably never ever rise again as it did in the past. The next months will reveal the fundamental flaws behind Bitcoin as the bubble will deflate further. I am predicting at least a few dozen suicides because of it, as some people that were so stupid to buy at the top will never see their money back. And that surely is not something I can laugh about, as I consider that a real human tragedy.
