--- Early Adoption Ends Here and The Price Stabilizes ---
Basically, buy and hold for three years as much BTC as you can. It's not unreasonable to think that the value will even just merely double or triple in the next three years, if the past three years is any indication. Perhaps it won't go to 1M USD, but it's within reach to hit 1K USD again.
1k is almost certain. But we aren't in it for just 1k right? We want 10k!
