I'm not sure I quite understand this. It has happened every single time I bought a coin. Whether it's BTC, VTC, XPY, BC, DRK or even LTC. It doesn't matter what I buy it shits itself as soon as my buy order goes through. As soon as I get tired and sell it starts going up. 
I think you're not alone in this crypto world, I also make many mistakes in crypto trading... i lose half on every crash panic selling and panic buying
