Maybe you right with bitcoin losing popularity with very lower price today, for October bitcoin never back to raise higher price and still down with $8 where last month bitcoin above $10k, will become bad thing for bitcoin losing popularity and give bad for altcoin price? lets give best for bitcoin can raise to higher price again and we need to get much profit with bitcoin investment for long time because only bitcoin become profitable investment.
Fluctuations will always be there as a part of bitcoin and crypto currency world as long as a group of people hold huge amount of bitcoin or until there is demand and supply which cannot be stopped and I believe bitcoin always comes back stronger but last 18 months has not been as expected but things will change don't mix up altcoins with bitcoin as they cannot survive without bitcoin.
