Everybody can be early adopters. The true early adopters are those who have bought and kept their BTC at a very cheap price. Is $5k-6k range of BTC price cheap for you? If you would consider the future value, it does not exist yet and nobody knows what it brings. All we can do is buy it, keep it, forget about it for the longest time, wait for the shocking news when BTC hits the mainstream news.
We never know the development of bicoin prices for the future, whether it can be as high as 2017 or just go up a little. So when we buy at the current price between USD 3,000 and USD 4,000, we just wait for the increase that is expected to be profitable.
