These stats are amazing. I had no idea Splinterlands was so huge. Do you really need to hire someone to manage your card rentals, though? It seems like if you could just tap into the dataflow and combine it with an analysis tool like Microsoft Power BI, Tableau, or some equivalent you would have continuous reporting at your finger tips. Heck, you might just be able to get by with Excel or Google Sheets.
So, you started with nothing in 2018 and you now have this performance? That's impressive.
