The earlier you are in the game, the more uncertainty you will have, the difficulty of evaluating the risk/reward is almost the same. Bitcoin was cheap back in 2010, but by that time it had almost no public awareness and everyone thought it is just a game
So it does not matter you enter the game at $1 or $1000, you will always face this very difficult decision making process, the market is fair
Even in a fully saturated market, there are 370K new baby born each passing day, means sooner or later they will be competing for 5000 coins daily supply of bitcoin on the market, so they averagely will get 0.0135 coin per person for their whole life, and that amount of coin is going to hold their life savings, for example 1 million dollar at today's price
Once bitcoin is accepted at official exchanges around the world, hedge fond and pension fond will start to invest in bitcoin, the race to this 1-100 million dollar per coin will begin
Seriously, anyone believes this? I have read in forums some guys mined bitcoin just for fun back in the day, and they are NEETs without any education, but they happened to mine a shit load and maybe buy some weed on Silk Road or what not. So you are saying that some high school dropouts that mined bitcoins for weed when you could get a ton per day, will be richer than Bill Gates in the future? Let's get some perspective on there. Im tempted to buy one at current price because im scared that supossed "correction" these crystal ball armchair economists are predicting never happens and it goes straight up to 2, 3.. 4K.. but saying this will be worth 1+ million dollar in the future puts a lot of random clueless people into the 1% powerful elite right there with the Bielderberg Grup. Think about it, will the powers that be allow for this to happen? Sure, you can say no one believed this would be 1000 back in the day, but to achieve 1MM, means no other software comes and surpases Bitcoin, nothing against it happens, no crashes (if it crashes, the credibility will be 0 because it isn't backed by the entire US economy and US military, as opposed to the dollar) and so on and so on.
I hope im wrong and people that manage to buy now 1 BTC will be very wealthy in the future, but im afraid we missed this boat a year ago. Oh, and what decides what purchasing power 1BTC has? If it needs other FIATs like USD and EUR as reference, then what would happen in an scenareo were other FIATs collapse? what stablished the purchasing power of 1BTC? I still need a reply on that one.
