No matter amount of Bitcoin mining reward, the short answer is always ASIC with best efficiency in terms of J/TH and good price/hashrate ratio.
I don’t think it is as simple as this.
Customers need to have a decent customer service/support if something goes wrong with the hardware and I don’t think there are many reputable brands around that provide it. Canaan used to be quite big I don’t know if they are still in business but Bitmain is pretty much the golden standard of crypto miners.
So instead of choosing a brand you never heard of before, OP you should go with a miner from Bitmain’s lineup imo. (Unless you are feeling adventurous)
Canada is still very much active, they have released few new BTC home miners in the past few weeks, one is named Q and others, they are quit cool and very efficient but I just like buying miners when the market is so terrible.
Difficulty will be lower because some miners will find it hard to run their hardware bacuse of grid power bills and also the ASIC miners will be a lot cheaper, I still think the best time to invest in a ASIC miner is in a blood market.
Those who set up miners when BTC was at $15,000 years back did very well already, cheaper hardware and more BTC that ended up having better value. This is my own way.
