Maybe I wont care if bitcoin keeps going up. Maybe one day just 0.02 btc or maybe 0.04 if I can put more in before the percentage of dollars to btc becomes so far off everything is negligible. maybe one day it wont matter if you cant own an entire coin. maybe 1mbt will be like what 1 whole bitcoin is today, or even just 1 satoshi will equal 1 dollar and I'll be a millionaire in that way. Or maybe my kids will be idk.
When the price of Bitcoin was below $1000, people could not have imagined that at any one time it would cost $10,000. when it reached $10,000, there was a lot of debate in people's minds as to whether the price could reach $20,000 at all!
The current value of Bitcoin, people could not even imagine in 2017. The price of Bitcoin has been rising continuously, avoiding everyone's perception. If you buy some bitcoin now, it will be safe insurance for your child. Future generations will be users of electronic currency, and Bitcoin will dominate the electronic currency.
