Altcoins are falling in price, so buy them more - sounds inconsistent. To diversify in the current situation, it is better to buy more bitcoin and some altcoins because the future of altcoins is very vague and the risks are correspondingly large.
The situation is really hard for altcoins since they are the most affected for this fall.
Actually, I'm not getting much confident as well for altcoins but somehow, I also think that Altcoin will never stick this remarkable market disappointment all the time. I know it takes time to recover and that is why I'm still giving a chance for altcoins to prove that they are still worthy for investment and trust.
