Craig Customer and Mark Merchant don't care about the tech below the hood. All they care is that stuff just runs fine and that they don't loose money during the transaction. Compare it with cars, does the average driver care about which type of engine the car runs? Nope, they just care that it doesn't break down.
Interesting point. A crypto coin has to work, today. That's all that matters.
Most coins are far too slow to scale up for real world transaction rates, and Lightning is misunderstood hype. But no one cares about that right now. Coins like BTC chug along ok and store value nicely, today.
Gulden 2.0 is supposed to be far more secure than Bitcoin. That makes me wonder about Bitcoin's known security flaws. If/when one of these flaws is exploited, does that mean the price of BTC (and most altcoins) goes to nearly zero in a couple of days? I guess the value crashes severely, and if Gulden 2.0 is deployed at that time, then NLG price changes would be very interesting to watch.
