I only invested in bitcoin because a friend convinced me to. If there is a new cryptocurrency, what are the parameters / requirements that would make you decide to invest on it?
You can quickly earn x2 and more only on young promising altcoins. I managed to multiply my state on such cryptocurrencies as OCN (x3), UPP (x3), SOUL (x2). In a falling market, profit is possible only on new coins if you are not greedy and sell on time.
