and i have an idea why company like paypal offer payment from user to user its more cheaper right
I am not a PayPal fan and I do not use PayPal at all. But, what I know is that this is not new at all, also if you are transferring on custodial wallets like coinbase, the fee is free. But, the mining fee is charged if you are transferring to another wallet entirely, but what PayPal can not provide as they only provide not bitcoin but just a number, which also is not transferable to a bitcoin wallet. PayPal users can not transfer bitcoin but can only buy and sell Bitcoin.
