MinerBoxes from PCPraha.cz or minerboxes.com can make the miner very silent. Or you can just buy miners like AL0 or KS0 for home mining (iceriver machines).
Of course, with these ASICs there will be quiet mining, but this does not mean that it will be profitable. You will give 1000 dollars for an ASIC, and then for 3 years you will receive 1 dollar per day 
If we take average profit values.AL1 PRO is profitable rn, you just have to watch the market and buy asap. Or the hosting option ofc with low electricity prices
Better then to look at the new A11 asic from DragonBall Miner, which is almost 3 times cheaper and its profit is almost the same.
But these asics are mining shitcoins, and the profit will drop every day.
Yes it will drop, like gpus and everything else.
The one thing that will happen is these coins will pump like hell during the bull market because the asic developers have mined a heap before release. Radiant is a classic example, asics have been on the network for months
but they have only just been released to the public
I've been mining Radiant on GPUs for a while, now I need to see how many coins I have. If the story with the Kaspa coin repeats itself, we may see a price of 1 cent on this coin.
But it will depend on the demand for new ASICs.
