Bitcoin price will drop with time due to transfer time, which now can be up to 3 or 4 days, with average fee 0.0002 BTC. Therefore people will switch to altcoins, which are much more fast, and Bitcoin price will drop, altcoin price will go up. Bitcoin Cash transfer for example take 20 minutes, Doge - 10 minutes. So this is time to sell your Bitcoins !!!
Another reason will be - large miner farms mine Bitcoins, but Bitcoin user group is the same and not expanding, so Bitcoins just loose its value due to large scale mining too.
I respect your opinion but nonetheless, it seems you know so little about bitcoin... It is always normal for the entire bitcoin network and this has been happening for quite sometimes now so it isn't something new. I believe the network is experiencing increase in the rate of transactions which results in the network clog. Bitcoin is the future, you should really learn more about it
