trying to imitate something that is already huge will not work most of the time.....more so if there is not enough money for promo and if it is just a plug-in
just because a sector is "hot" will not make it "hot" for the company trying to embark in that same sector...
if it is "hot" it is partly because it is massively popular with fierce competition...
A "hot" sector means very strong competition
Promoters would like to seduce you with such keywords as "current valuation" of a certaint sector, "hot", "massive", "giant" ect...but be very aware that it absolutly does not mean "hot" opportunities, "massive" opportunities, or "giant " opportunities .....as those words can only be attributed to that sector NOT the company trying to do the same...the company trying to do the same will not automaticly inherit those keywords just because that sector has those qualities
The hotter a sector, the more competition a company will have to cut through to be noticed, hence originality and enough money to promote are the two most important factors. A plug-in or several plug-ins bolted together is not original because anybody can do the same.
As an analogy, although the movie making sector is a hot one, even if you are the top actor/actress in your class it will not make you a superstar making millions just because there are actors/actresses making that much. Because quite simply, the competition is unimaginely fierce. Therefore do not get seduce by the big social media money makers. There are very specific reason why they got there for which 10s, 100s of millions of users is one of them reasons.
