I just checked twitter and bitmain is starting sale of l3 and d3 in few hours, My dillema is if i should keep my btc to pay for canaan order(if they will ever send btc payment address) or try to get miner from bitmain which wont ship until end of year.
I already managed to pay for one D3 (late november batch) but i'm not even sure if dash mining will be still profitable by the time i will get it.

Any advice?
Thanks
