We at Quantum1Net believes what needed is higher amount of data transaction and speed, lower power consumption and stronger security.

You have spoken about the technology side in your thread. It certainly needs higher amount of data transaction and speed, lower power consumption and stronger security. But then what? What to do with lightening fast speed and strongest security if there is no market? So let me talk about the economical perspective here,
1. Market for crypto currency:
It is the main thing needed for a crypto currency to survive and thrive. Today, we have a massive online market of crypto currency where people are are buying and selling it, but when we look at the goods and services market, we see a big blank space. We have a very few options where we can use our crypto currency for regular purchase of goods and services. Whatever small options we have, that is too restricted by countries. So we need our merchants to accept crypto currency for a healthy crypto ecosystem. Here technology can bridge the gap currently exists.
2. Regulations:
It might sound awkward but it is true. Regulation can make the crypto market shine like a moon. Over 90% of the world population are very conservative about their finances. These percentage of population would not try anything new in their entire life if that particular thing is not approved and regulated by their government. The statistics looks shocking but it's true. The members of these community don't come under this percentage hence it will be hard to digest, but try talking to your grandparents about crypto currency and ask them to invest in it, you will understand the fact. If crypto currency is adopted and regulated by a majority of the government, the entire market dynamics will change for better.
There are other factors as well. However, these two are the basic factors which will help crypto currency to be adopted by the common mass. Obviously we can't think anything less about the technological aspect of it because we will need to infrastructure to support this market and technological advancements is the only we can achieve that.
