Bitcoin long-term investment/trading for sure. Alternative coins Most of the times, short-term investment. Long-term investments in altcoins depends on how good that altcoin really is, other than that, none of the altcoins are worth long-term investing, for me.
I, too, do not consider alternative coins as long-term investments. But some of them are good as short-term assets.
Bitcoin is good in both long-term and short-term investments
