Im probably selling my s9 units when they arrive in march this is looking bad AF, bitcoin price, bitmain releasing miners like crazy, difficulty going up and now samsung joining
Thats the wisest thing you can do at this stage. It would be even better if you could sell them now as a pre-order with promised March delivery although that concept does not seem to fly anymore either these days.
Ive been monitoring the price of miners selling on Ebay since I sold mine last month and they have been dropping faster than the value of BTC.
Every miner now is selling for a couple of hundred bucks less than the one before.
