Welcome to the world of crypocurrency. If I were you, I wouldnt be making any purchases this week. There's a possibility of a lot of volatility. Take this time to watch as many YouTube videos and read as many white papers(I know it sucks) as you can. Cryptos are here to stay, there is no rush. Go to Coin Market Cap and look into the top 10 initially, then top 20. Go to their websites.
