Investing in multiple coins can be leasing if you are not an expect in the case that you can get to loose track of ypur investment so i asvice you invest in just one or two coins and face focus on them only, that not been said i advice you buy BTC and any other alt of your choice
i will only invest to the coin that i think has a potential seperating your investment will be a good way but only invest in waht you are trusting most .
