Not sure why they are doing this but lets look at the deals they are offering.

So you can burn your miners:

You get 1000 ECOINs for each 85,000 Gh/s or 10% bonus from the miner you burn

So what can you get for ECOINS

So for the 1.080 Ph/s or 1080000 Gh/s server it would cost you

27500 ecoins 

1000 ecoins for 85000 Gh/s so you need 2337500 Gh/s (2.3375 Ph/s) for the coins to get the miner

2.3375 Ph/s in power for less then 1/2 the same power back.

Why would you trade in miners. I don't get why they think this is a good idea. If you got all the bonus miners for turning in at the different levels it might be worth it 

Even taking into account the miners you get for burning

1000 gets you shifter 40000 Gh/s

5000 gets you 8bubbled 165000 Gh/s

10000 gets you CameraMiner 210000 Gh/s

25000 gets you Steamwheeldle 360000 Gh/s

42500 gets you Golden Fleece 500000 Gh/s

65000 gets you AncLA 724000 Gh/s

90000 gets you rollerMillion 1000000 Gh/s (limited to 1500)

or another 2.999 Ph/s so now it may be worth it but that;s a hell of a lot of miner to burn.

They need to learn to make more reachable levels and rewards to make it worth doing.

So you can gain power but it'll take way to much time and loss of power building up to the power you might gain. I don't think I have enough miners to gain the advantage of turning them in.

I have about 5 Ph/s of mining power but no way to tell what is miners and what is game play, but I'm not risking my miners and time to play this event.

So my advice is start saving for a room upgrade to add more space, I used 20% of my mining power to get RTL and now have 3 rooms, 2 full of racks holding tons of low end miners making me more RTL and Solana for now
