I dont know some, But if you buy now BTC maybe in the future it will go to 1000 dollar. So let say 1 BTC = $300 over one half year (maybe) than you have earn 700$ doing nothing
Well that is just nice thinking, but you never know.
The recent surge shows we truly don't know. No one speculated this to happen price so quick. It's really nice to have it happen.
We are still a way's from 1k though. Lot of time to get there, and some up's and down's for sure between.
