Nano brought me here but guess everyone hates it?

So you can say I have been living under a rock while I found crypto fascinating I was never really invested in it neither mentally nor monetarily.

Well yesterday nano giveaway reeled me into crypto world and I really loved the eco friendly, fast, and zero fees thing about the nano coin but I have read many negative comments about it on here.

I though of many implementations of it. How it can make transactions global, easy and instant. no payment gateway, no conversion, no bank account integration that’s really awesome but I planned it all with nano in mind and now I am hearing not so good things about it.

So, what’s the deal with it? If it’s not that good what are the alternatives with similar features? Simple to setup, fast, zero or low fees and widely known.
