After watching Philpa’s video https://www.youtube.com/watch?v=GUzcksaIku4 , this is my conclusion :
Buying 520,692 ADA is just $22,389.756 dollars with the price at $0.043 only to get $3.76 daily by staking? I’m sorry but I only need to invest $1,800 dollars in a 3 GPU Mining Rig of AMD Radeon VII that yields $3.84 daily … for the time being mining is more profitable than staking with less money. Cardano ADA needs to compare its profitability with is closest competitor Mining. I’m comparing this ADA example with real crypto mining, please avoid comparing this example with FUTURE price of ADA, that is just daydreaming.
