Well you are completly wrong right now, its true that the demands of bitcoin has reduced compared in December 2017, there is a lot of factor that makes bitcoin demand reduced. First people used to using bitcoin to invest in ICO and right now ICO is seems not profitable and not much ico are success now.

I do think you also wrong if you said alts have increased in price, cause what i see right now the entire market is going down and not only bitcoin is down, ethereum, neo, eos and others alts are also going down in value too.
