My portfolio dollar value is increasing but the satoshi is dropping. Why?
It is as OP says the price increase in BTC have only 2 reason
First there are new money that gets in on the market,
Or second the bag holders of alt-coin are just switching their alt to BTC.
And base on your folio it seems that most of your holdings are being traded to BTC and that is the reason why your Sats folio is getting low while your dollar value increase.
