It sounds like you must Enjoy having Blockstream's dick shoved down your throat while your paying $100+ to move your coins off an exchange.
Tell your grandma to buy Bitcoin, it's a great investment. I'm sure she will love the part where she has to calculate a priority fee to pay based on the size of her transaction.
For everything else, there's Bitcoin Cash.
What sort of idiot is in bitcoin to spend them in b/s?
It's just you.
Yeah, because the thousands of people who have disconnected themselves from the banks and from FIAT don't exist.
Legacy Bitcoin has been taken over by corporate interests that want to prevent BTC from scaling, thus removing competition and ensuring their monopolies will continue uncontested. No one is going to want to pay $20, 30, 40, 50$+ fees to make a payment or just to move coins. Thus, Legacy Bitcoin has truly become a Banking Settlement Layer - with fees comparable to a bank wire, and confirmation times comparable to a bank wire. This is Bitcoin now. Enjoy it. It's what you wanted.
