Waves is a great coin in my opinion, I see it going $50+ this year and $100 next year.

Here is where you can buy it - https://coinmarketcap.com/currencies/waves/#markets
You can also buy it directly in the DEX - https://waveswallet.io/

Once you bought some, you can lease them out from the wallet to earn more + airdrops each month
