Different cryptocurrencies have different vision. When I got to know about smartcash https://smartcash.cc/ I was first attracted to the smartrewards feature. A person can earn smartrewards by putting smartcash in the wallet and not speing it. I think this is supercool feature to easily earn a crypto simply by holding it and not having to mine it with expensive equipment.
I got further interested in smartcash https://smartcash.cc/ when the concept of smartnodes emerged. By running a smartnode a user can earn even more smartcash. I find the awesome.
Next big attraction for me is being able to load smartcash onto the ATAR wallet and use it like money to shop.
Though I have not been able to try this feature but some day I would. So smartcash has become one of my favorite cryptocurrencies.
