Almost all altcoins are now making new all time low, Gala games for example look like it's going to 0.015$ after holding 0.025$ for months, I have halted my buys right now because I believe that BTC will go lower, what are you plans?
Bitcoin is going lower and lower because we are in bearish market right now. Most of the altcoins are going down because usually it's following Bitcoin's price mostly. At least if you don't need emergency funds and would like to take a risk then would be better to just hold it. Otherwise, you can cut losses the loss and wait until the price is most likely "stable" for bit longer.
