Yes, its a big issue, people are not doing enough research before investing in a coin or token. Doing our own research is essential to get it right and to avoid centralized Shitcoins, were the developers can make everything they want. Bitcoin has a strong Code and decent Developers, so it's our best bet to invest in Bitcoin. 
Stuff that's centralized will blow up one way or another, or be put in such a situation that everybody will be reminded of its status.
Whereas with BTC, there won't be any hiccups like that.
