Hmm I agree! In long term Bitcoin won't hold current value. If you compare it to nearly every other Cryptocurrency out there it really lacks in transfer costs and confirmation speed. I really do not see Bitcoin on top of the list (market capitalization wise) at the end of 2018. Especially for services needing micro-transactions other blockchain technologies will take Bitcoin from its throne.

Although I do not see it retracing as low as $1K USD. It is and will always be the first thing popping in someones mind when talking about Cryptocurrencies or the Blockchain technology.
