ETH... and good ICO projects 
Lol! Is there any good icos now? I bet it just those who are afford to pay their signature participants with btc. But the rest are mostly scamConsidering the current market situation, it seems to me that a long-term hold of altcoins is a bad idea. Too much uncertainty in the future, so if you are looking for something for a long-term, it is better to choose bitcoin. Altcoins, on the other hand, are better to use for short or medium-term deals in order to quickly increase capital.
You're right. Why waste your money into shitcoins if bitcoin can be a certainty to give profit. While I don't think some altcoins can give a decent earning since the altcoin price is normally base on bitcoin price.
