need advice on feasible blockchain project ideas

[aucoinmaster]

Recently read over 100 pieces of whitepapers by recent ICOs or companies which have been in this industry for several years.Find some problems with these projects:

1.Most of them cannot be implemented or may be implemented with much difficulty
2.Few of the projects quote the actual cooperation with established companies,not to mention insert their technology into these companies
3.Whether it is necessary to adopt blockchain and ICO for each project?This is also a big problem as I can not find convincible evidence to support their statement.

As I am currently searching for some blockchain project ideas ,but i find this is a challange for me due to the problems above as well as many other problems which I did not mention.

Let me list some areas that I think maybe feasible:

1.cryptocurrency exchange
2.digital identity
3.work history verification
4.get compensation for flight delay
5.car rental
6.authentification for high-end merchandise ,like handbags.
7.supply chain management

Also,these areas are currently non-feasible(my opinion):
1.decentralized casinos
2.ecommerce
3.healthcare records
4.transactive grid
5.property registration

I hope to get some REAL opinions on which areas we may enter into in order to develop a feasible blockchain project which can be implemented in our real life or respective industry.
