#why the %%% percentage changes so sporadically?

I don’t know if it’s me or this is happening? If you have noticed this or happened to you please leave a comment.

I have noticed and this happened to me few times where I am watching a coin and the coin is at a specific % percentage and the price don’t change so much that it would make a dramatic change in the percentage, but yet suddenly this percentage either drops or goes up much higher than it supposed to. Which in fact as we know this will change the sentiment of buying or selling. So this is what I think: this happens to push or drive down the price of that specific coin. And infact this makes gaining or losing money in the market. Again I could be wrong but it happened few times and noticed it and wondered.
