Last night, the blockchain was a bit congested. I tried to transfer some coins and ended up stuck in the mempool, like when a delivery arrives downstairs but the rider refuses to come up... You think once you click, it's done, but actually, it’s first broadcasted out, and miners/validators pick and pack it. If you set a low fee, you can only wait; during this time, your transaction might get bumped by others, or even if you try to speed it up or cancel, you have to pay the "queueing fee" again. Usually, at this point, I stop first, observe, and stop checking the market. Anyway, I’m a dollar-cost averaging and rebalancing guy, so a few more minutes or hours won’t break me. Recently, everyone’s been talking about modularization and the data layer, and developers are super excited. As a user, I just care about: don’t let my regular transfers get stuck in the queue to the point I start doubting life. That’s it for now, just wait it out.
