If the price will ever stabilize, what are the factors we need to look out for as investor to know that the time has come for us to apply extraordinary wisdom ?
There is actually no possibility that Bitcoin will ever become a stable currency. In fact, there is no such thing in the Bitcoin protocol.
And if something like this existed in the Bitcoin network, Bitcoin would never have reached its current position so quickly. If bitcoin had increased in price at an average annual rate of gold like 7%-10%, then it would have taken more than 10 million years for Bitcoin to reach this price.
So, I think it's sometimes not a wise idea to waste time worrying about all these things.
