Do some research before buying anything on the internet lots of sites sells bitcoin but some of them are scam. You did it right because you asked before you bought bitcoin and just explore here in the forum if you are a beginner
Yes, it is good to seek opinion first before buying some of these coins, because the way we have many of these very terrible projects now is really alarming, and I think we need to be very watchful on all of them.
As much as we have scam projects and scam exchanges, there are still lots of very great projects and exchanges that we have in the market, and some of them can really be seen as the ones that are ranked the top exchanges and coins, they have too many great community for one not to sport them easily.
It is only when we are going for some of these low quality exchanges that we get scammed, and when it comes to purchasing of bitcoin, I think there is no point looking at any other exchanges other than exchange like Huobi and others.
