My sps airdrop points

I don't make that much from the airdrop but with just about 100 usd worth of cards I make about 30 usd per month which is the best roi I have ever seen. If I'm not mistaken with just 1k usd investment you will make about 160 usd per month. Tripling 1k usd in a year? Sounds too good to be true but it's actually possible and you can even make more by playing the game and staking the sps .
