Can anyone sell me $20 in xDai, for XLM or Paypal? It costs too much gas to use the bridge.
There are also two fiat on-ramps (Ramp Network and Mt. Pelerin) and AscendEX CEX with free direct withdrawals to xDai.
If you need just a little bit for gas, you can use the faucet: Faucet | Gimlu.com, or I can send you some.
Those services do not offer xDai in the U.S.
