Finally, most projects present blockchain as a pill for every malady. But does it really make sense for that particular industry? Is it possible to implement the same project without a native token? Is blockchain tech a decisive factor in the final products infrastructure, or it could work pretty much the same without all those distributed ledgers and smart contracts? Does it really disrupt anything but your patience for the word disruption?
Blockchain technology can be implemented in so many products and industries, but not everywhere too. Of course, there are so many fake and scam projects claiming that they want to involve blockchain technology in X domain which isn't the case obviously.
That's why you have to study the project carefully, and especially reading the whole whitepaper.
