Too ambition to imagine BTC at $100000 in year.
I'm sure many people said the same thing about 10k this year. I don't think we will see 100k next year, though. I could see it easily being worth 20k+ in 2018, but I can also see the opposite and the bubble bursting after the excitement has died down and it falling to 4-6k again. I hope I'm wrong though. If we keep spreading the word and people keep buying in then we should be safe as long as we've got the demand to meet the supply.
I think that this decline will not happen. Bitcoin popularity is on the rise. Capitalization increases. Of course, I can't confidently assert that it is not pumping bitcoin speculative capital. But I think that in parallel with this, an increasing number of common users. I believe that next year the developers decide to increase the size of the block and bitcoin will become popular in the trade. This can significantly increase the price of bitcoin.
