I think we can still hold altcoins like ethereum, lisk, litecoin, zcash and dash the foregoing coins has done very well in the past and there are still doing very well today no matter what is happening. Some of this coins could have gone into extension if not for how strong there are.
So yes you are right about that but the loss in the values of Altcoin has deeply hurt people and some of them who had been around for some time have also left the market. Only the long term guys are going to stay.
