miners selling is not down, they are still selling their coins as before since they have the same costs including electricity bill as before. what has been "down" is the number of coins that miners have to sell which is expected as they are now earning 50% less than before and it is a big contributor to the overall decrease of sell pressure on the market as a whole.
There's also a ton of money the past few months just sitting in stable coins - likely people holding back waiting to see where the market will go.
first of all that would never affect bitcoin price. and secondly if you check the shitcoin, i mean altcoin market you will see that it is not true. the "stable coins" are going in and out of shitcoins that are being pumped and dumped every day specifically because bitcoin price is stable nowadays (for nearly 2 months) which is a pretty common thing for many years where traders migrate to altcoin market to pump and dump shitcoins.
right now 24 hour
trading volume of tether is $5 billion higher than 24 hour trading volume of bitcoin. when bitcoin starts rising all that volume goes into dumping shitcoins and converting it to bitcoin. again tether doesn't come in during that process and won't affect bitcoin price.
Seems to me the only thing holding bitcoin's price back right now is short term bearish or more likely uncertain sentiment.
i completely agree specially with bold part. bitcoin investors have always had the tendency to be uncertain every time price becomes stable like these days. they prefer waiting for a signal to jump in rather than accumulating at the bottom. that is why we see stable prices be followed by a big FOMO
