Yes, previously we invested in many in development coin which makes us lose money in the market. Recently you can see there are some projects which will help to develop what they mentioned in the roadmap. So it is always good to research before investing into anything.
You are right it is not very hard anymore to get information about any project, now all over the world internet is spreading information highly to make people aware, it is not good to invest blindly even in this age of digital, if we will discuss with others even in this forum so we will not face any scamming and we will feel safe for investing our money to bitcoin, now in increasing number of coins my trust is one and only bitcoin.
