@cryptographic - Sir after reading your valuable blog today & I understood why people keep saying why BTC is not sustainable... Cost & Speed are the two major concerns... But with BTC we can't see low cost, high speed solution... Specially mining consume lots of power & it's not good too Sir...
Nice you decided to talk it... I think Sir you are suggesting us to stay with BTS & STEEM like you said in your previous posts... I'll do Sir... Thank you...
