BTC supplier? I'm pretty sure most of the coins are held by traders at this point in time. And miners have no choice but to adapt to how the coins are currently priced by the market.
I really doubt that theory. Who's have
BTC1 Million bitcoin that he generated through the mining process the first time? Then more people mining as well, early adopters are the miners, so we can conclude the miners have so much bitcoin = or we can call them the real whales.
Traders buy bitcoin from the miners but still, they (miners) have so much left in their wallets and keep coming from the mining process.
