Yeah there are many hidden and overt factors out there for sure affecting the market. I think that lack of retail funds that we saw enter the market at the end of 2017 reflects that depressed price too. Ultimately it is very hard to beat the market - often it beats you instead lol. Even when you hold a ton of coins the market can turn on you in a dime - and in a market that never sleeps like cryptocurrency stuff can happen even when you are sleeping!
Ultimately just remember not to overextend, do not invest more than you can afford - that way downturns don't hurt as much, hopefully.
