Are there e-wallets in Bali that can be topped up with crypto?

Yes, such wallets exist in Bali and Indonesia in general, and they can be a good replacement for a bank card, especially if you know how to use crypto exchanges and make P2P exchanges. There are at least GoPay, OVO, LinkAja, ShopeePay. We recommend getting GoPay or OVO. More details about these wallets, which one is better to get, how to top up, and where to use them are described in the instructions here - https://nashaplaneta.net/asia/indonesia/money#ewallets
