If someone bought $100 of Bitcoin in 2010 and kept it until now, they would now have around $6 million.
Do you think the same could happen again in the next 7 years? If I now own $500 in Bitcoin could that be worth $1 million+ in the next 7 years? Or is it extremely unlikely for this increase to happen a second time?
The question should be, do we know what the future holds? No! If we all knew as at 2010 that bitcoin would be worth about $6000 this period, wouldn't we all be extremely wealthy by now?
The irony of such assumptions is that if all the peeps from 2010 had known that Bitcoin would be worth about $6000 in 2017, the price would have never reached these levels simply because many of these early birds would have been just happy to sell their coins somewhere below this mark but certainly above what they had actually sold them for. Therefore, the price might have never gotten where it is today.
