If I think, falling altcoin is normal ... before stepping forward to make a decision we must be prepared with all the risks, usually altcoin always based on bitcoin, when bitcoin up altcoin also rises vice versa.
Altcoin is always subject to the fluctuations of Bitcoin so the sharp decline of the BTC has caused altcoin to fall sharply today. The market capitalization has fallen more than 20% in the last few days and it is a very strong drop which has created a great psychological panic for investors.
