I can tell you that $1 000 000 is life changing in South Africa, and although I am still far from there, the investment is growing. Splinterlands definitely grew a lot and with the airdrop it is still far from over. Then there is things like 3Speak, which has the potential to grow a lot as new Hive users get onboard and get to know about it - imagine it goes to only 10% of YouTube!!
I hope it keeps on growing!!
