Not really. If you closely pay attention to how Bitcoin has increased in value, and how the sentiment has been more bullish than ever before, you'll understand that you're wrong. Various altcoins have indeed gained a certain form of attention, but that's mainly due to the fact that people are stunned by the sheer increase of Ethereum, and thus invest in other altcoins in the hope that they will experience the same level of growth. Ethereum without the ICO hype would be sitting below Litecoin's price at current levels. I am not an altcoin fan at all, but the only altcoin I do somewhat appreciate is Litecoin. It has maintained its value extremely well throughout the years. All other alts are straight junk.
