People mainly use cryptocurrency for investment purposes. And for investment people mainly choose bitcoin and Etherum. These two are best for investment. Bitcoin is best for short term investment and Etherum is best for long term investment purposes. I don't think any other cryptocurrency except these two are profitable because other cryptocurrency are not have an impressive market price yet. And they are not so much famous for investment purposes too.
