If you have good trading experience, I think you can buy altcoins like ethereum, xrp, eos and ltc.
there are a lot of new coins even I can't mention them one by one, the Ico project is a good step when you have friends who can convince you to buy coins at ICO, but before you invest in ICO make sure they have clear products and project goals.
At present there are many projects that do not hold ICOs and you can do your own research on the altcoins you want to buy to get a profit in the future
