i think statistically 1 from 50 undervalued project can in future experienced high increase of value....so if we currently have aproximately 1400 coins -- there are udoubtedly some sleeping giants which are at the moment under top200 coins in coinmarketcap and their value is very small, but in the future thanks to good inovation they can easily replace coins which are currently in top30..
2. there also are too many ICOs --- most of them doesnt give any sense and the projects will not survive for more than 2 years, but if you make good research, separates good projects from bad and you find something unique, something what can be milestone, can influence other projects and doesnt attract too much attention, wit little luck your investment could return 100times or perhaps more..i think we should focus on projects of which technologies are trying to upgrade blockchain or are developing own blockchain which is better, more advanced, which offer more than only simple smart contracts. Or focused on something similar to blockchain-but not blockchain as for example tangle from iota....
i personally like this type of projects:
1. https://gpower.network/ -- it could be very usefull for all smartphones producers to enable users to fully charge their battery in 5 seconds, also usefull for electric cars producers such as tesla....
2. projects which are focused on quantum technology and post quantum encryption as for example or developing their own blockchain resistant against attacks from quantum computers -- QRL, MOCHIMO, SIRIUS SMARTCHAIN, partially IOTA and Xtrabytes .....
3. projects developing blockchain 3.0 related with things like decentralized applications, cloud services or supercomputers..--- GENARO NETWORK, ARCBLOCK, SONM, GOLEM...
4. projects developing decentralized blockchain cryptocurrencies but deflationary-self destructing based on proof of burn....QUANTUMPROJECT https://www.quantumproject.org/
5. projects developing decentralized blockchain cryptocurrencies based on proof of importance PoL, proof of stake velocity PoSV for example reddcoin, proof of capacity PoV for example burstcoin or Kucoin, proof of deposid PoD - so far any project..
6.project developing interledgers- token transfer as for example RAIDEN NETWORKS or INTERLEDGER PROTOCOL
if you know some other, or something interesting - do not hasistate and share
Great post and valuable !! Thanks
