Is it possible? Sure. Does that mean the market this for sure going that way? No, nobody knows and if they were for sure they could make a lot of money and wouldn't tell anyone. (But knowing the future isn't real)
Yeah, it sure as hell doesn't look like the market is going to be moving on pace to hit $50k in a year. I agree it
could happen, but it just doesn't seem likely at the moment, does it? On the other hand, nothing would really surprise me as far as bitcoin's price swings go and I do think there will be a rally at some point between now and the end of next year.
The abundance of altcoins doesn't have much to do with how bitcoin is going to behave IMO. The size of the bitcoin community basically dwarfs all of the other ones and if any coin is going to achieve close to a 10x gain in a year, it'll be bitcoin. The rest of the altcoins are just tagging along with it.
