we need to ignore trolls and dumb people then only we can get success in our life that is what you are really doing people who call Bitcoin a scam will realise what is bitcoin after few more years but they will have to pay a very huge fee for waiting that much period at the time you can't laugh at the just for being so much dump.
Those kind of op statement dont even thrill me, because we have so many people that their thinking sense is so low and they reason like a blind person. One thing we just have to learn is never to follow peoples opinion or allow them to dictate what we do without life and money. I tell people like him that it is my time, my life, and my money so it is none of his dam business.
I get advises from those that talks with words of wisdom but not people like him that are full of speeches that are with very low quality. People have their level of patience and they all have the way they plan their life, so if somebody invest and decide to wait for eternity, then it is own business and his the one that knows what he has seen in the future of whatever he engages himself with.
