Those miners sold out.
When D3 , L3+ , S9 become available on bitmain website , usually 30 minutes or less and sold out
OMG, that's strange. When will there be a new batch? I would love to purchase some of those miners because I want to build my own mining farm and I feel it's much better to buy L3+ and D3 for mining because Bitcoin mining is not that profitable now as Altcoins.
