Coinbase has fulfilled its promise of integrating Bitcoin's Lightning Network, partnering with Lightspark to bring users instant, low-cost bitcoin transfers. This move aligns with their vision of a one-second, one-cent global payments system, challenging the slow and expensive traditional finance model.

With Lightning support, users can opt for faster, cheaper transactions, complementing the existing Bitcoin network. This integration not only enhances user experience but also strengthens the broader Bitcoin ecosystem, with major exchanges like Kraken and Binance already onboard.

Previously, Bitcoin transfers on Coinbase could take hours and incur hefty fees. Now, Lightning enables instant off-chain transactions at a fraction of the cost. While not yet available in all regions, this development marks a significant leap towards mainstream crypto adoption and a more efficient financial future.

So I recently got my hands on the Coinbase Visa Debit Card and wanted to share my thoughts on it. This card promises 0% transaction fees on all purchases, which is a pretty big deal in the world of crypto. Just to clarify, this card is different from the one they've had for years on a separate app. This one is built into their main application and seems to work better overall.

The costs:

Card and delivery were both free. I transferred funds from Revolut to Coinbase via SEPA transfer with no fees, and I also traded EUR to USDT with no fee. The only fee I encountered was when I traded Bitcoin, which was only -0.06 EUR. Keep in mind that the fees depend on the amount you trade.

I can't say for sure that there are absolutely no fees for crypto payments, as the price of the coins was changing during my tests, and even USDT went down slightly. There may be some hidden fees, like exchange rate, but they are negligible - you'll be more impacted by the market condition and timing. I tried Bitcoin and Tether, and both had similar results.

Overall, I think this card is worth getting for every...
