one of the shortcomings of the digital currency from some other shortcomings is that the market can be manipulated by big investors because prices depend on volality so they can set their own price.
I don't know what are you talking about mate, there is a possibility that the big investors can make manipulation in the market or those big politicians that want to manipulate price and keep spreading FUD news to discourage small investors and do the panic selling. Probably that happened many rich people can play the price the bitcoin in the market.
Lucky for us that we know everything here regarding bitcoin price manipulation we don't act panic selling because we are already aware.
For those who are aware and do have experience on how this market moves then i would say we do have the advantage but not totally exempted on possible loss. We are still at risk yet we dont know on when those manipulations can happen. Hard to detect since we arent part of whales unless if you do have insider info then its possible but most of the time we dont have those kind of informations which we are still considered the same for those people who are investing to the market.
