Oh that is great choice because altcoins price are very cheap, I think you should learn yourself about god coins from markets, study about the project about which coins you invest, Now days lot of altcoins are creating every day so many coins are scams also, whenever you invest any altcoins study thoroughly and read roadmaps,white paper,team active in social medias etc.. Invest in different altcoins that will reduce risk This is the most stable and most popular cryptocurrency, which will grow in the near future. I think you can buy some altcoins, but also leave a little bitcoin in your wallet. It takes a lot of time to analyze coins because right now there are so many bad projects and it is so easy to make mistake
