Research your idea. See if there's a demand. A lot of people have great ideas, but they don't know if there's a need for it. You also have to research your competition.

Great ideas originate in the muscles.

In life, a lot of great ideas sound insane or absurd at first.

Great ideas germinate and blossom in the fertile minds of only those who follow their passion aggresively without bothering about voices around to do things differently with an objective to serve entire society and humanity.

Great ideas comes only in absolute need, however those who create needs with their ideas are Great!!!

With great ideas come great changes. Bitcoin's that.
