Well, based on this thread which I just created before I saw this one, I personally assumed 2 million satoshis to be a good number to hold for those who feel they are too poor to afford more, based on the current price of one satoshi today which is around $0.000366 like i mentioned in the thread I shared above, 2 million satoshis will worth around $732 dollars, and if you can be patient enough to hold it till 1 satoshi hit 1 cent, then your 2 million satoshi will be worth $20,000 dollars, if it hits 10 cents for each satoshi, then your 2 million satoshi will be worth $200,000 dollars.

The ball is in your court, so it's up to you to decide.
