I could definitely see an extended correction like Bitcoin's back in 2014-2016. However I think this is where the true Bitcoin competitors with shine and rise to the top. With Bitcoin's growing popularity we've seen some real issues coming to the surface, namely: transaction fees and transaction times. These issues primarily stem from Bitcoin's 1MB blocksize cap, this is a great starting point for other coins to address and differentiate themselves. Regardless of all the speculation on where Bitcoin and the rest of crypto will be tomorrow or next week, I don't think we can truly say that bulls or bears are "right" until years down the road...
