Glad there are still so, I would say realistic people. Certainly it is now the right time to buy as much BTC as you can, in such situations people just need to rely on professionals' opinions, like Winklevoss, for instance. Not sure if they have a deep knowledge about BTC and how it works, but I doubt that they would invest millions in something not worthy, even if they're not professionals themselves, they definitely hired one of the best consultors. Unfortunately, lots of people think that they should know better.
I agree. Of course if you are new to this business you must research and seek advice from Hero or legendary members or any members here who are more knowledgeable. As what I have known, it is best to buy coins as its low price and since it is volatile you just keep track of its price and trade it when it is at its highest peak or when you think you can achieve the profit you want.
