3 years is long time in crypto. It's a high growth high volatility market. Crypto is pure tech and innovation. Just look at the Moore's law. Just look at how much technology can change and advance in 3 years. Blockchain space is getting into the mainstream which will become a catalyst for everything. Just look at BTC from 3 years ago and now. Look at how far things have come. I can say the same about Dash, Maidsafe and a whole lot of coins including ETH which weren't even a thing 3 years ago.

3 years is a long long time.
