I think that we will reach the top of the bubble for at least 2-3 years. The market of crypto-currencies should reach a capitalization of 4-5 trillion dollars.
Yes this is going to happen soon, because in the last year we all have seen bitcoins were not welcomed in such a fantastic manner. But just see the price rates at the end of year that was astonishing. They were jumping like frogs and crossing so many thousands within a day. And we hope for such a charismatic response from bitcoins that they may reach $30k this year.
