No matter if it's legal or illegal, more than 25 % of the world population are living with less than 2 usd a day. They will never get close to bitcoin.
That figure does not reflect their actual worth as those people probably farm the land and live in houses they built themselves - thus most of their economic activity is not measured in money.
Even so with that money you can still save up for a Bitcoin card or as a small business a solar panel and an old android phone. If this gives you access to the entire world financially they may well deem it worthy.
Some very successful businesses already micro finance Indians so they can get a small lamp and a solar panel to use for studying or selling hot dogs at night.
Well that might be true enough, but consider this: What would the value of Bitcoin be if it was used "only" by everyone sick of the current system in the world? If it was "only" used by small to medium sized pioneering businesses in the world?
I think more than 1 billion $ market cap would be a safe bet.
Do you realize that it means around 50 usd / bitcoin?
Not with only 11 mil coins so far. When we have 15 mil coins BTC will be mainstream.
Bitcoin might have some advantages and could be used in some areas / websites or for very specific matters, but it will never be used a lot in the world, and not like you said.
I have made predictions before and been rather spot on. The recent bubble I predicted months before it happened as well as the crash. I even made 1 BTC betting about it with one guy.
This is a pretty big picture one so maybe things will go a few years slower or faster but I will be right in the end - mankind has never found a new superior technology and NOT used it.
Even if Bitcoin itself is somehow broken, the users will just download a patch, roll back the blockchain a day or two and the price will climb back up after a year - I know this because it already happened 2010 where they found a SERIOUS bug.
The whole concept of bitcoins is flawed. When you make a transaction, you need a instant confirmation. For instance, if you pay something with your credit card, you want to be sure that the required amount was paid. And you can't wait a few min / hours / days. Bitcoins confirmation (and not transaction) are way too long.
if you are paying for a coffee, 0 confirmation transaction is good as the secure one.
A coffee is worth 20 cents. Bitcoin is not really designed to handle such small transaction.
No it is not.. but it will be.
The protocol allows for it, its just a question of when we have nodes working together to store and validate rather than doing it all by themselves. When that is programmed (and it WILL be by SOMEONE when Bitcoin goes to a 100 billion market cap in some years).

Bitcoin will be the same and with just that market share the price would be at least 10 times higher than now.
