It will be quite hard given the fact that there will be only 21 million Bitcoins ever and at least a million of them is already out of cirrculation due to lost privkeys etc.
It doesn't really matter much if that much has been lost because 1 bitcoin can be separated into smaller units. Bitcoin doesn't have to be completely 21 million in numbers to be able to accommodate everyone in the world. The decrease of bitcoin in circulation actually kinda helps for the price increase of bitcoin since it will be more volatile.
How do you really know that, Bitcoin would hit 250000$ at year 2022.
There really is no way to know what will be the price of bitcoin at a certain time in the future so anyone who claims anything like this is basically just guessing that's why I never really trusted speculations although it's sometimes fun to hear their "explanations".
I want to respond to your thread title about the purpose of creating bitcoin, I think the purpose of creating bitcoin to date has not been achieved because satoshi assumes that a good currency is not controlled by the government or central bank. As long as bitcoin is still a tool of investment without in use as a means of payment , bitcoin has not reached its destination.
You can use it as a way to pay but only for digital transactions. Transactions IRL are mostly paid with fiat money which you can buy with your bitcoins. So indirectly you're buying things with bitcoins. It will take a long time before we can directly use it.
Bitcoin's main goal is to become a world currency. but that is impossible with the reason that the limited amount of bitcoin is only 21,000,000 in the world.
where might divide 21,000,000 bitcoins for the whole world. it won't be enough.
bitcoin is more suitable as an investment asset.
1 bitcoin can be divided in much smaller units. It's not like we're supposed to have 1 whole bitcoin, 2 whole bitcoins.
It grows because of the HYIP and no more,this is the problem and the demand will fall and bitcoin will not be needed, there are many altcoins that are more profitable than bitcoin .
Don't be crazy. Altcoins are only profitable in the short term. Altcoins die right away. Once the majority of the bounty hunters have dumped the coin, it's very unlikely that the coin will have anymore future. As you can see, most altcoins don't really have a future anymore. It's profitable only if you're lucky enough to dump before everyone else. Otherwise, you'd be losing money. I'd put my money in bitcoins instead and just wait out a couple of months. It's a lot less risky than holding an altcoin only to find out the next morning that the devs are already gone and everyone has already sold their coins and your money is basically gone.
