This thing of; that I heard or someone said "such a thing" about bitcoin on the negative side is old, retrograde speech, as I commented in another thread today, it is speech from bitcoin's past.
Those who arrive are welcome, those who don't, ok, have a good time, it's that simple, so! you don't have to blame anyone or invited, come on, history repeats itself, there are a hundred investments that have been ignored in the recent past, you go to the 20th century and review, many of the best evaluated companies today were undervalued, hence many missed the boat, but it is normal, everything is based on trust.
Compare to my Bitcoin investment when I was still new? I was just ready to take the risk is all, trust alone can't do this since investing on Bitcoin demands money, I was ready for any possibilities even before knowing more about Bitcoin, this was why I get to know Bitcoin better, so imagine if there are more people like me in the world today.
Some people are not been told yet, but believe me, many people are opportunists when it comes to something that could work or may not work, they are always ready to take risks, but if the word of Bitcoin never reached them they won't know.
Because of my past experience, that's why I still keep telling people about Bitcoin, humans are full of different spirits and minds, not everyone will talk nonsense about Bitcoin, the majority did though, but few numbers of people that I told about Bitcoin have the same mind as I have.
