Only one of my questions, is bitcoin really ready to be used as a currency? Because, we both know. There are still some obstacles to bitcoin if it is used as a payment tool. Especially regarding transaction speed and transaction costs
Yes this statement might be true. Holders will not change the world but they could change their world by holding. Holding until the price gets high could make themselves profitable when they sell their coins in the market.
But the real question should be whether the holders are really going to change the world for the better if ever. What is it in holding that makes it so beneficial for the world? Personally, I can't come up with anything which justifies holding apart from personal gains by selling when the price hits the sky. From my perspective, it is effectively just a postponed consumption which is not a good thing in itself.
Am I missing some important detail in the grander picture?
Hodlers will change the world for better and I consider myself one of them, because we can do the best what we can do for the price to soar higher. If we don't hodle, then who can do it for us? The whales always look out for a good timing when to take over and be back to track. Price will have to be profitable as long as there's more demand to happen, and investors like big whales along with long term holders will patiently wait for the right time as well.
