Which cryptocurency to invest?

Buy some Bitcoin and wait a couple months. When Bitcoin floats under $2300 here and there, that's when I buy in. It always floats back up to $2700, $2800, and $2900. The price can literally fluctuate that much in a week so if you commit to buying a piece of BTC when the price is below a certain amount you can make some good cash every couple days. IF, you have money to invest.
