There are several good coins to invest in, BTC and ETH are safe bets, but you won't see the returns that you will with the lower priced coins. One coin I really like is a privacy coin called DeepOnion, it's ATH was a little over $20 USD, and is currently around $3.10, such an undervalued coin at the moment. And their community is so awesome. You can join the free airdrops will increase your investment, also they have bounties, and contests all in which you can earn free onions. Check out the community here: deeponion.org/community, Good luck on your investments!
