Your Bitcoin or alts investments may be down, but part of investing is about taking risks and taking the rough with the smooth. As i result of the prices crashing, your investment plan shouldn't be over, only delayed!
Bitcoin needs to overcome it's scalability issue before it can flourish and it's these issues that are impacting the entire crypto market.
The Btc price dump has had a massive affect on the entire crypto market, billions of dollars have left the crypto space, people are selling due to fear of loss. I've come to realise that the only time you really lose and make a loss, is when you sell at a loss. If you're holding alts at a loss, hold, you could make a profit tomorrow, next week, next month.....
When people are selling and alts are red, I see this as a buying opportunity to grab some cheap crytocurrency and bitcoin.
Summarising: Hold and enjoy the cheap alts market atm!

Never trade / invest more than you can afford to lose into the crazy world of crypto.
