BTC is struggling. Many people are bullish that it will be strong in 2018.
For those who think that, why do you think that is the case when fees are so high and send times so slow?
BTC is the best cryptocurrency among all and no matter what is the present valuation of BTC but it will surely rise again in the future because for now it is not merely a cryptocurrency, it's an asset, a resource which will be very very useful in the future. BTC has provided employment to millions of jobless people and millions are investing into BTC because of its potential that it possess. So according to me the valuation will definitely inflate again.
