That's great @mmaarrttiinn11. Indeed it is a great tool to learn how to use cryptos, especially for people who don't have the means to buy it. Also, BTC's transaction cost is very low at the moment. It's around 96% lower than its all time high. And the lightning network is still not usable for mainstream transactions yet as there's still some major issues to fix. However, it will certainly solve bitcoin's network congestion issue or aka scalability.
