They're buying much because they understand that it's going to be the game changer in the world of investments. Many people are still in the common shares of investments and don't want to dive in with new technologies like blockchain and bitcoin.
The main reason why traditional investors took so much time to dive deep into the cryptocurrency market is because of high volatility in the market and now we are seeing institutional investors trying their hand by investing heavily and if their success rate continues then we might see more investors pumping their dollars in the market in the coming years and the negative aspect i see is that we will see a much higher volatile if these huge investors starts manipulating the market .
That's one reason.
And the other reason that I see is that it's still young. They don't want to take the risk unlike many of the cypherpunks who strongly believed with what it can do in the future.
Now, what they've believed is already happening and what was speculated before about prominent people, celebrities and governments are starting to really show their interest on it and not just it, they're actually doing it.
