I invested over 54 steem and bought 9k sports during its early days when it was still trading for $ 0.006, now I have over 100k sports staked.
I also invested I think close to 15 steem on MOT but it's currently like a bad investment for me.. Will be unstaking and selling soon.
Staked little (all the steem i have at that time) on marlians but it is a great initiative that I will surely invest more later.
