It would be cost prohibitive to do that. You can't tip anything less than the current BTC transaction fees, which are currently $15 https://bitcoinfees.cash/ @davidshares
Imagine tipping ~500 sats for 15USD...while the recipient will never be able to move it. mAgIc InTeRnEt mOneY @thelegendarytwatter
Read.cash should also allow tipping in BTC. People need to experience scaling issues first hand, rather than just be preached at. @n00b
It already allows to fund your account with BTC throught SideShift ("Deposit" > "Other Cryptocurrencies"). This is enough to see the scaling issues! @lugaxker
