I think, that now is good time to buy btc and altcoins too. As you see, their price is getting down. Probably, their price will grow up and we will get big profits. I suppose, that it's good time to participate in ICO too. For example - ElonCity. This project is interesting and looks perspective. One of the biggest reason to think so is its partner - Krypical Group. They had four partnerships and they were all succesful. Probably this will be too.
