look at altcoins market price is now very low, all altcoins its price down, I want to ask, whether at the end of the year altcoins prices remain down, or will rise?
End of the year is still 6 months away. If anything, the price of altcoins is only going to increase towards the end of the year instead of falling down. This current phase is the one where market is collapsing and a surge in the prices of coin is just a few weeks away.
As of now you can take this golden opportunity of investing in cheap coins so that once they grow you take the maximum benefits out of it. In this current market there is dearth for new investments and hence the price has not been growing as it was during december, but all that would change in the coming days. Do not worry at all.
