Bitcoin is divisable, up to 0.00000001, which is called a Satoshi. So you don't need to buy an entire Bitcoin. It's not expensive to get into Bitcoin at all. Bitcoin can be bought from a Bitcoin exchange, like Coinbase, Kraken and others. Some people call Bitcoin bad for the environment because it costs lots of energy to mine it. I think coal energy is bad for he environment, not Bitcoin. Bitcoin mined with renewable energy is not bad for the environment at all. Some people think that energy is wasted by mining Bitcoin, in which case I understand why they think Bitcoin is bad for the environment. However I'm of the opinion that Bitcoin needs to exist in this world, it will fulfill an important role in our monetary system. |
That's exactly what he means. By divising it up in smaller and smaller increments, instead of the 'old way' increasing the money supply, you safeguard the wealth of rich people and increase their wealth over time. The opposite of inflation. For example a bread that first cost 1 bitcoin, now costs 0.1 bitcoin so people can still buy bread. Inflation is in a way an equalizing factor where the hoarded wealth of the rich becomes worth less over time. Fixed or dwindling supply, requiring going to smaller and smaller denominations promotes inequality.
Using green energy to mine bitcoin is still bad. Imagine putting a million environmentally friendly cars on the road, electric, charged by green energy. They don't do much, just drive around randomly. (carrying the ledger around) They still need a lot of resources to be build and recycled at end of life. Just like all the computers that go into bitcoin mining. It's not just about the energy they use in operation. They also generate extra traffic. Bitcoin is just a drop in the bucket compared to all the other internet traffic but it still needs a fast internet connection from remote energy friendly places.
What is the important role that Bitcoin will fulfill?
One thing I don't quite understand is how does Bitcoin or how do you see your account balance. Is there a database encrypted with the most current hash somewhere, or does the entire blockchain have to be parsed each time to calculate your account balance? The blockchain of bitCoin is now 360 GB and keeps growing with each transaction. It already takes quite a while to get a copy of the blockchain but at least you only add to it at the end. Yet parsing this ever growing file to get your account balance can't go on indefinitely either?
