You don't like seeing more onramps into bitcoin?

Anyone receiving Celo from the promotion can transfer that to an exchange that supports that token, like KUCoin, and sell that token for bitcoin.

Also, coincident to this promotion launching on LocalCoinSwap there is a bridge service called LN-Celo, which lets those with their free Celo convert that into Lightning network.

LN-Celo was created by kriptode, ... whose products are built by the person that created Redphone, which @k00b describes here:

Building things with Lightning for fun & microprofit #1440

LN-Celo public launch is imminent (this week yet, I believe).
