Hello, I have been watching the price of ADA coin (Cardano) go up these days. Yesterday at some point it went +145% in some hours. What I am asking is, what did the price go up so sudden? Something happened or just a lot of people invested and bought the coin and the price went up? And then they will all sell and the price will fall? Sorry, for the noob questions, I am just waching the numbers and trying to understand the market.
