Hey there Entropy-uc,

Can you back your statements with data?

For a setting of 50 DragonMint 16Ts ($1,710/pc including power source) = $85,500, today's profit is 3.1 monthly BTC according to Antpool: https://www.antpool.com/support.htm?m=calculator

ROI is around 1.5 months after purchase, even considering electricity costs.

Besides, the hardware itself doubles its value nowadays when in stock, so the return on investment is 200% already since the moment you receive the miners.

What's your opinion on these numbers? Do you see any flaw in my reasoning?

The only problem I see is that the difficulty increases every day, and from yesterday to today, according to this very same calculator, profits fell by 15%. I opened a thread about this today.
