Buying a little RBTC for 1 donation the long and hard way... but remember there is an easy way too!

I was trying to buy a bit above 0.0011 RBTC but I hadn't over calculated enough, I should have gone with at least $62 instead of $59, which also means I should then have spend yet a higher amount at the MoonPay exchange, $3 to $5 extra would have done the trick.
