I think you already conduct a research with these coins you chose. Just want to suggest consider investing in btc and eth as well. Its safe to have a well-established coins in your portfolio so if something unfortunate happen in other coins that you invest in you can count to those popular coins to still standing. If you have doubts you can always search what could be the best coin to include in your crypro portfolio.
I often think twice before deciding to invest and spend a lot of time researching because any project will have its own risks if not careful. Of course, I just like to invest in new coins because these are usually the coins that bring huge profits to investors and receive great attention from everyone. However, not every project is lucky enough to have a good price because the crypto market is very volatile.
