If I think Bitcoin is likely to be stagnant. And finally a new Bitcoin will be born who will have problems and this remains (as well as many others like Pow), and dying then will eventually die. I personally think I'm more curious as to why no one has implemented instant payments in altcoin. I heard that Dash would do something like that but the people here quickly disprove my suspicions. Litecoin also wanted it, but Wu and the company seem to have stopped this process as well.
 Bitcoin will be jammed at some point at some price point, it will not rise but and still fluctuate around that circle in my opinion. For the current price, Bitcoin will still have a large movement, a steady increase every month / year but people can not use it like we use fiat money if not measurable.
Perhaps someday another unmeasured cryptocurrency will surpass the Bitcoin price and market capitalization in general.
