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.
It’s not out of place for one to expect the worst for most of these centralized coins but the mile in which Ripple continue to wallet just surprising but, a show of the resilience of the team behind Ripple development.
Even with the news of one of its founders having to liquidate some of his holdings which should have shook the community behind Ripple to take profit, it’s somehow endured and keeps being on the rise.
Even then, they still don’t come any close to Bitcoin which operates a decentralized system and Bitcoin investors don’t really view Bitcoin for a take profit and short term investment as is often the case with these altcoins, Bitcoin is regarded for a currency of the future.
