The Bitcoin mining business is in a great position as investments have paid off and now that BTC is on the move for the final rush of the 4 year halving cycle the profitability of these mining firms will be solidified. Very few newer faster miners available because of the Chinese crackdown and semiconductor shortages. Very hard to find mining equipment. These mining machines with BTC above 50k pay off in 9 months, above $80k 5 months. If BTC hits $150k HUT 8 and BITF are money printing machines. But be careful to be out of your big positions by March. Track BTC price and you will know when to scale up and scale out. Unless they have a shelf offering sitting out there and run one like Hut 8 did it should be a fairly quick run up over the next one or two quarters. Up 16% yesterday the call options placed the day before were handsomely rewarded, but the IV will eat you alive so get in and get out unless you are selling options and even then try to do it on consolidation weeks. To be safe you could wait until she clears the Ichimoku cloud on the 4 hour timeframe.
