It seems that the price of Altcoin has stopped in one place and is getting lower. If the price of Altcoin stays at that fixed point, then it is very difficult for the price of Altcoin to fall. If the price of Altcoin now becomes too high, then people will start buying more and more, which will cause the price of Altcoin to go up. Is that right?
Your right, the market is all about demand and once the demand will become thicker then the price of every currencies will increase. But you should also consider that the market is full of many types of investment and one of the investment type that really affect the price of the market are the traders.
If there are big trades that happened then the market will surely be affected and that is why there is no steady increase of price instead there are little setbacks even in the bull season.
