$2 million is more than enough to lead a comfortable retired life.
Eh? in my country this value only serves to buy a comfortable home, but the person will not have a comfortable life for one year with 2 million dollars.
Do not need to rush to reach $6800 or more than $7000, most countries will legalize bitcoin in the future and many companies will accept bitcoin as a means of payment.
Of course, if you are living in developer 1st world country the $2 is not something that amazing to have, certainly not a fortune to dream about at night.
But $2kk is not a small amount either, I bet that if you will invest your hypothetical $2 million in Bitcoin now, then if the near future you will double, triple or quadruple your investment.
Anyway - on one hand, I would like for bitcoin to grow really fast and high, but at the same time, I am aware that there is a high chance of bubble exploding, and I am a bit scared of rapid growth.
