in my opinion this is just a manipulation, we don't even know when prices will be normal because there is always manipulation by interested people and it destroys everything
It doesn't destroy anything, It is just a normal thing to see manipulations once in a while, it is only rampant here because it is a decentralized market, there is no law or regulation in place against manipulations, and the market is highly speculative.
With respect to the speculative nature of the market, until we start getting to see real life usage before we can get to start seeing real demand and adoption and less of manipulations as no whale will obviously want to get burned.
