That way, everyone would wait to buy until it gets stabilized.
You will lose minig profits if you wait.. it makes zero sense to wait. The price isn't dropping fast enough to justify waiting nor should it drop that fast.
The reduction made in 2 days is 2599 - 2529 = $70.
With a single Terra you will not earn $70 in 2 days. You will earn $54 minus the electricity, making it less than $48.
Where am I wrong?
The price the S2 is at is too high - Bitmain is focused on bringing it down to reasonable prices 1 day at a time, just like when they jumped the S1 price down from 0.8BTC to 0.6BTC to catch up to the difficulty trends.
The S2 has 10x the chips and 5.5x the speed of an S1, but still costsa about 11x the price of an S1. That makes it less appealing as a purchase
There are 640 chips on S2 and 64 on S1...right?
So... if 64 chip S1 = 0.45 BTC (with coupon)... 640 chip S2 should be 4.5 BTC .... Current price of S2 with coupon is 4.695 BTC --- I am sure the additional 0.195 BTC covers the PSU cost.
It only makes sense to purchase multiple S1s if you have access to very cheap electricity in this case 10xS1 at $0.1 kW/h will give you better profit margin then just having 1xS1... Majority of us unfortunately pay anywhere from $0.15 - $0.3 kW/h for this reason S2 makes sense for some people. Obviously there are other issues like having enough room for 10xS1, or the amount of power it is required, heat issues etc...
Only way I can see it making sense is that Bitmain Tech to release a smaller power efficient chip.
But heck I could be wrong.
