None of these will provide HUGE RETURN
There's no way you or anyone else can say this with certainty.
How many threads do we have to dedicate to this topic. It's like a fucking broken record, repeating over and over and over. Which altcoin do I invest in? How about you invest in an English course and learn to get past that ADD and READ. Less typing, more eyeballing. All of you halfwits who start these topics: READ. You don't have to keep starting multiple threads asking the same thing. People are just going to give worthless tips anyway! Do you think if someone knew what the next hot thing is going to be, they'd tell you? Don't be naive.
And, I invite everybody to skip answering such questions. This causes lots of meaningless threads and increases the chance to read valuable threads/responses.
